    BMW E90 Performance Software: 2005+ Cars 

    The Fastest Way To More Power - Up To 120hp!!!

    Our Performance Software makes more horsepower and torque with no downsides! Performance software is the icing on the cake, the finishing touch, or the capstone for your BMW tuning project. Software ties it all together - maximizing output from upgrades where the factory software can't keep up. The factory software is actually programmed around 87 octane which de-tunes the performance of the car. Our software is set to 91 as a mimimum, allowing us to be more aggressive with the programming. We can refine and adjust the factory limitations, opening up the potential for more horsepower or refinement from your current upgrades. We also tune the software to fix defects and rough edges in the stock software, making the car easier and more enjoyable to drive.

    We have been tuning BMW software since 1995, making us one of the most experienced BMW tuners in North America. Over the years we have experimented and tested many different forms and brands of performance software, including developing our own on our Dynapack chassis dyno. Our Performance Software catalog includes tunes and upgrades that best suit your BMW and your upgrade goals.

    Turner Motorsport Performance Flash Software features:
    + dyno developed, real-world tested
    + ignition and fuel timing adjustments
    + cam timing, including VANOS and Valvetronic
    + raised rev limit*
    + top speed de-limited*
    + part throttle and full throttle mapping
    + improved throttle response
    + specific software for most major upgrades - cold-air intakes, sport exhaust, etc
    + race software for removing catalytic converters**


    Software for most 2005 and newer models is done in-house via a reflash of your computer. A 'flash' is copying your stock software and replacing it with our new, modified version. Your engine computer will need to be sent to us for the upgrade.

    * - on select models
    ** - not legal for street use, emissions liability waiver required

    BMW Performance Power Kit - E9x 335i, 335xi, E82 135i with N55 engine   (more info)
    Looking for more power from your N55 equipped 335i or 135i? This BMW Performance Software Upgrade provides a 20hp gain while retaining the factory warranty. With sporty performance, outstanding driving dynamics and innovative technology, the Power Kit maintains all of BMW's key attributes but allows you to put a personal touch on your BMW. The Performance-Optimized Engine Software provided by the Power Kit increases torque to 332 lb-ft (automatic transmissions) or 317 lb-ft (manual transmissions) available from just 1,500 rpm. Power output is increased by 20 horsepower, from 300hp to 320hp. This results in faster acceleration from 0 to 60 mph (0.2 seconds faster than the standard model) and from 50 mph to 75 mph (0.5 seconds faster than the standard model). Even with this increased power, the fuel consumption and emissions ratings remain the same as they were with the standard model.

    HP gain = 85+ hp
    Trq gain = 100+ ft-lbs
    Plug-In Power! Easy to use and completely reversible!
    Expect higher gains with additional modifications


    The Cobb Tuning AccessPort is a flashing tool that installs performance software through the OBD port on your car. No other software is as easy to use and install! If you can program a TV remote, you're over-qualified to install this software. Just plug the AccessPort into the OBDII port under the dash, bring up the AccessPort onscreen menu, select from a variety of engine maps for your desired performance and install. It's that easy. The software is from COBB Tuning - one of the most accomplished software tuners in the business. The Cobb software replaces the conservative factory settings with different maps to make more power.

    The AccessPort maintains the sophisticated control logic, refined engine response and excellent driveability of the stock BMW computer while providing impressive power gains and improved performance. Pre-loaded on the AccessPort are engine maps for 91 or 93 octane fuel, and a valet mode, with the capacity to hold up to 100 other tuning files! The AccessPort also saves your stock tune for you to revert back to factory settings at any time. It also has the the ability to download additional maps so that you can run various upgrades with the correct software tune. Additional tunes are available direct from Cobb through their AccessPort manager program (available for PC or OSX). Cobb also provides tech support.

    In addition to the performance improvements, the AccessPort includes a variety of other useful tools -
    + performance measurements
    + data logging - up to 10 hours
    + fault code/DTC reading and clearing
    + check/verify performance modifications - measures 0-60 and ¼ mile times and can measure approximate HP

    The AccessPort can display boost pressure, oil temperature, pedal position, load, individual cylinder timing, and other engine data channels with the Live Data feature.

    GIAC Performance Software for BMW 135i, 335i, 535i (N54 Engine)   (more info)
    GIAC Performance software for the 2007+ BMW E82 135i and E90/E92 335i 335xi

    Dyno developed performance software for the 135, 335 - and it makes AMAZING POWER! +70hp and +80lb/ft of torque over stock! That's 330.7 hp to the wheels and 359 lb ft of torque, as measured at the rear wheels -- just imagine how much power that is at the crank! Can you say faster than a M3? There are no down sides of this modification, other than needing 91 or higher octane gas. We modify fuel and spark mapping, adjust the valvaetronic (throttle), and most importantly INCREASE THE BOOST to a safe, reliable amount.

    This is the perfect upgrade for someone who wants a dramatic but safe boost in power -- especially in the low to mid-range. Check out the dyno sheet: with the Stage 1 performance software your car will have MUCH more torque at ALL RPM, including down low (where you want it) for remarkably better torque. This is HUGE torque that is a NIGHT AND DAY difference. If you are in the Boston area, make an appointment to stop by for a road test. Our 335 with this software is simply "Nutty!", as others have put it. 91 or higher octane gasoline is required. Please keep in mind that with a "turbo car" it is "easy" to make horsepower by increasing boost BUT keeping your BMW reliable is the most important thing to Turner Motorsport. Others may claim to make more power to make our software seem a little conservative, but we're confident this is the perfect compromise -- the most power made within the safe limits of your engine. Much better than the alternatives. If for some reason your dealer "reflashes" your car with stock software after you purchase this from TMS, we will reflash your ECU with our software at no charge (except for shipping). Also available is stage 2 software , for race /off road use only. Stage 2 Software features front Cat delete. Click here for dyno results.

    Stage 1 includes: Software upgrade

    The software re-flash is done through TMS. Your (ECU)computer will need to be removed and shipped to TMS. We can usually turn it around in one day, leaving your car only down a short time.

    Turbo Tuner 2 for 135i, 335i, 335xi, 535i & 535xi   (more info)
    New improved version, with advanced features! The Turbo Tuner 2 is a more advanced version of the popular Turbo Tuner, a plug-and-play solution that significantly enhances performance. Typical gains of the Turbo Tuner 2 are 40 horsepower and 50 ft-lbs of torque. Both the Turbo Tuner and Turbo Tuner 2 are easily installed -- this updated version 2 adds a user adjustment, allowing you to fine-tune the additional boost the Turbo Tuner 2 provides. This updated version also adds a wire harness extension, which allows you to locate the adjustment control in a spot of your choosing, for easier access. Dial up/down the boost as needed, in seconds. The connectors and wiring on the Turbo Tuner 2 have also been improved to provide additional strain relief on the cabling, assuring trouble-free operation over many cycles of installation and removal. There is simply no easier and less expensive way to make such drastic horsepower and torque gains on a BMW, period.

    Turbo Tuner Dyno Results for 335i, 335xi, 135i, 535i, 535xi The Turbo Tuner 2, like its predecessor, can be installed or uninstalled in seconds. It does not cause any trouble codes and its operation does not leave any trace that it was ever there. The Turbo Tuner 2 is not an ECU re-flash solution. It is an embedded control solution, built using surface mount technology and state-of-the-art pick-and-place assembly equipment, that works seamlessly with the stock ECU. The turbo tuner provides real performance gains while it preserves the smooth and refined character of the car. It also features a soft limit circuit that avoids overboost, protecting the engine from boost spikes and preserving drivability. A temperature compensation protection circuit lowers boost at elevated under-hood temperatures for further protection. No special tools or expertise required, and full instructions and support are provided.

    The internal setting is accessed by removing two screws and the cover on the back of the unit. The setting adjusts the additional boost over stock. With a setting of 100 the unit will request an increase of 4 psi over stock. The actual boost will depend on several factors including the octane of the fuel. On the later model years a 2D25 manipulation prevention code can be set if the setting is too high. It is a good idea to check with a scan tool to make sure that code is not being stored. Turn down the setting if necessary.

    This part alters or deletes the emissions equipment on your car. Because of this, we require a waiver of emissions compliance to be signed and sent in to TMS. You can download the waiver here.

    Turner Performance Software for E9X 325i   (more info)


    Max HP gain = 19 hp
    Max Trq gain = 15 ft-lbs
    Rev Limit = 7000 RPM


    The 2006 325i came with the same N52 3.0-liter engine as the more 330i. But BMW made several changes to de-tune the 325i (to justify the additional cost of the 330i). Thanks to tuners like us it's now very easy to unlock the potential of the 325i engine to meet the 330's output. Our Stage 1 software is a simple re-flash of the stock software, yielding a gain of 19hp and 15ft-lbs of torque! The gains made by this software between 3500 and 5500 are simply a night and day change!

    Our software fully maximizes the N52 engine in 325i spec. The stock BMW software is hampered by settings for 87 octane fuel. By re-mapping the engine programming for 91 octane, we can make more power, torque, and improve fuel mileage - all without harm to the engine or affecting driveability. We have paid particular attention to increasing low and mid-range torque. The throttle response is also improved (quicker) eliminating unwanted and dangerous flat spots in the pedal response.

    To get the full 330 output, you will need to change the intake manifold and use our Stage 2 software. We can also tune for a cold-air intake, exhaust, and headers/sport cats (another big power source).

    Our software fully maximizes the N51 engine in the 328i while in SULEV spec (Super Ultra Low Emission Vehicle). The stock BMW software is hampered by settings for 87 octane fuel. By re-mapping the engine programming for 91 octane, we can make more power, torque, and improve fuel mileage - all without harm to the engine or affecting driveability. We have paid particular attention to increasing low and mid-range torque. The throttle response is also improved (quicker) eliminating unwanted and dangerous flat spots in the pedal response.

    This software file is for the N51 engine SULEV model only. SULEV is a specification used in some parts of the US where emissions compliance is critical (mostly in California, the Northwest, and the Northeast). The computer and engine specs are different than the 'regular' 328i N52 engine.

    Rev Limit = 6900 RPM


    Looking for more punch from the turbo in your 2011+ 335i? This is the perfect upgrade for someone who wants a dramatic but safe boost in power - especially in the low to mid-range. Our software opens up the N55 engine's potential, delivering big gains in torque from idle all the way past 6500 RPM! The torque is especially improved after 2500 RPM, eliminating a pesky dead spot in the factory programming. This is a HUGE torque that is a NIGHT AND DAY difference!

    Our software is not just an increase in boost; we're not fooling the computer into making boost. This is a total re-write of the stock software, making power by adjusting the ignition and fuel mapping and boost. We have tuned for part throttle response as well as full-throttle with special attention given to ensure the correct, and safe, air-fuel ratio. Please keep in mind that with a "turbo car" it is "easy" to make horsepower by increasing boost BUT keeping your BMW reliable is the most important thing to Turner Motorsport.

    Turner Performance Software for E9X M3   (more info)
    INSTANT POWER GAIN WITH NO DOWNSIDE!
    Max HP gain = 17 hp
    Max Trq gain = 16 ft-lbs
    Rev Limit = 8300 RPM


    Adding power and torque to your M3's V8 is as easy as a flash! Where we can make our software better is by tuning it for 91 or higher octane gasoline. The stock software is tuned around the 87 octane available in the US (not that most people would use 87 but BMW engineers accounted for that possibility). With our software, the performance of the S65 engine is optimized. We tune many areas of the engine programming - fuel and timing maps at part throttle and wide-open throttle, VANOS variable valve timing, crisper shifts in SMG, and more. The throttle response is also improved (quicker) eliminating unwanted and dangerous flat spots in the pedal response.

    If you have other modifications done to your M3, we can supply you with specially-developed software to maximize the gains from those upgrades. Select all those that apply in the list below.

On our own M3 project vehicles, this combination netted 40hp and 32ft-lbs of torque* - a massive transformation to an already impressive output. Our Race software makes use of the same features of our street legal Stage 1 software - altering ignition timing, fuel mixture tables, and VANOS operation with the added benefit of using a racing exhaust without the front or back catalytic converters. This software has specific changes for the cat-delete to turn the check engine light off and prevent the car from going into limp mode. An optional 8600 RPM rev limit is available (stock is 8300). This product is for the software only and should be combined with our front cat-delete pipes (click here) or similar front-cat delete section.
    * = software alone, +40hp/+32ft-lbs when used with Test Pipes that remove the primary catalytic converters.

    If you have other modifications done to your M3, we can supply you with specially-developed software to maximize the gains from those upgrades. Select all those that apply in the list below.
