    Our most popular product hands down with tens of thousands sold since 1995! We offer Performance Chips developed by legendary Bosch tuning expert Jim Conforti as well as our own dyno-developed Turner Motorsport custom chips. Turner Performance Chips provide the ultimate in performance advantage! Adding a performance chip to your BMW is the easiest and most cost effective way of increasing BMW power, torque, and performance with NO DOWNSIDES. Through years of BMW performance tuning, we are able to maximize power and torque gains for 91 octane fuel used in North America. By making changes in the ignition and fuel maps of the DME we are able to optimize performance with no side effects or compromises. On most models we also safely raise the rev limit and delete the top speed limiter. Other changes will make your BMW smoother and more responsive than when it left the factory. Our chips have a lifetime warranty and a 30-day satisfaction guarantee. If for any reason you are not fully satisfied with the increase in power and overall driveability you can return the chip to Turner Motorsport for a full refund. Chips are supplied with detailed instructions and are user-installed in about an hour.

    FREE UPS Shipping is included with any Turner chip priced $249.95 or higher and shipped within the 48 US states. Free shipping applies to the performance chip only and is credited at time of checkout. Please note: for Air shipping, additional shipping charges will be applied when the order is processed.

    Turner Motorsport Chip Upgrade Policy: Turner chips are upgradeable to newer versions for free within the first six months. After six months, the upgrade fee is $100, applicable for custom chips that are equal or less in value of the original purchase price of the chip being traded in. The upgrade program only applies to the original retail purchaser of the chip. This program only applies to software upgrades listed in our catalog and being purchased for the same model of vehicle. Chip trade-up applies only if the upgrades you are installing were purchased from Turner Motorsport. If the parts that require a custom chip are sourced elsewhere other than Turner, the upgrade program does not apply. This program does not apply to dealer/wholesale accounts.

    The easiest software flashing tool in the world! Power & Torque Upgrades in Minutes!

    The Shark Injector is an amazing hand-held unit that plugs into your car’s diagnostic port and re-flashes the computer with performance software. The software was developed by renowned BMW tuner Jim Conforti, who has nearly 20 years of BMW engine tuning experience. The Shark Injector is one of the safest and most cost-effective enhancements you can do – offering features and results that other upgrades simply cannot touch. The Shark Injector will also be upgrade-able through its own USB port, allowing you to upgrade to different software as your needs and modifications change (under development).

    Why you will love this product -
    + more power and torque, particularly in the mid-range from 3500 RPM to redline,
    + quicker throttle response, giving the car a snappier feel,
    + a safe increase in rev limit (great for staying in gear just a little longer)
    + smoother-running engine with fewer hesitations and dead spots
    + top speed limiter removed
    + true DIY install with step-by-step instructions (no downtime while your computer is shipped somewhere else for the install)
    + Upgrade and Restore features to install/uninstall on the same vehicle
    + Upgrade-able via USB connection with your PC - add a file to better suit your mods (under development)
    + Retains all of your diagnostic, service, maintenance systems and won't interfere with your normal maintenance routines

    This software is a major refinement of the stock software. It makes the car much easier to drive with less hesitation, more torque, and incredibly smooth operation. A lot of tuning has been done at the low RPM ranges to improve response. The car won’t hesitate or lag, making the car easier to drive. And with the extra torque you can drive in a higher gear and not have to downshift as often. Theoretically this means better fuel mileage too!

    How does it work? The Shark Injector makes changes to the stock BMW software in the areas of fuel enrichment, transition fueling, camshaft timing, ignition timing, and VANOS control to take full advantage of 91+ octane fuel. BMW ‘de-tuned’ cars for the North American market in the event inferior fuel was used. We reverse those changes to gain more horsepower and torque. 91 or higher octane fuel must be used.

    How does it install? The Shark Injector plugs into your car’s On Board Diagnostic (OBD) port, located under the dashboard in most cars. At the push of a button the Injector begins communicating with your car’s computer. The Shark handles everything from that point on – reading and copying the stock software, re-loading its own performance version, and checking its work along the way. The whole operation is completed in under 20 minutes. A battery charger with a continuous 10-20amp charge is required (available below if you do not currently own one).

    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.

    + dyno developed, real-world tested
    + ignition and fuel timing adjustments

    For full race or track-only cars, an aftermarket engine management system provides enormous benefits over a stock ECU system. Modern ECU systems are not designed for racing and track use. The engineers have different goals in designing these systems compared to what a motorsports engineer would specify. Racers don't have to be concerned with emissions compliance or OBD diagnostic regulations. All a racer wants is lots of reliable power. And that's where aftermarket engine management - stand alone ECUs - come into play.

    We offer stand-alone engine management systems and components from Bosch Motorsport and MoTeC and others. Turner Motorsport has been racing with stand-alone systems for over ten years and have extensive real world experience with building complete systems, existing integration, and providing individual components for upgrades. We have also partnered with Bosch to develop a plug-and-play Motorsport ECU that is integrated with factory wiring harnesses.
