BMW Engine Performance Packages

Since 1993 Turner Motorsport has been at the forefront of performance tuning for BMWs. We show this best in our tuned Performance Packages, developed along stages for specific BMW models. Each staged Package is tuned in-house, bringing together expertise from our street tuning division, service shop, and race team. Nearly all of our Packages feature custom-tuned performance software from the best names in the business. The software is the best feature in our kits, maximizing power gains while doing nothing to affect engine reliability or driveability. In most cases, Stages are upgradeable - you can jump from one stage to another by purchasing the new parts and revised software (contact us directly about buying parts outside of the Stage). Or jump right into a higher stage by purchasing the complete kit. We'll work with you to select the appropriate parts and a matching software tune. Nearly all of our Packages have been tested and tuned on our in-house Dynapack Chassis Dyno. Our packages are designed for US-spec models only.

2007-2010 E90/E92/E93 335i N54 Stage 1+ Performance Package
Peak Power Gain*: up to 103hp / 108ft-lbs
+ aFe Pro5R Dual Cone Intake
+ Wagner Front Mount Intercooler
+ Cobb AccessPort programmer

More power = more heat. It's easy to make more power one time but to continue making that power consistently requires careful planning and design. With the additional boost the air entering the engine is also warmer, making the intercooler more important than ever. In testing, the stock BMW intercooler was quickly overwhelmed and cannot keep the intake air cool enough. The engine computer recognizes that and dials back the boost. A more efficient intercooler will keep boost levels up, delivering consistently higher boost levels. The Stage 1+ package includes a Wagner Evo I plug and play intercooler upgrade. We get great feedback from our customers and technicians about the Wagner FMIC - it's a direct bolt in part using all of the factory piping and it offers 85% more surface area than the factory intercooler.

The aFe Dual Cone intake and Cobb Accessport programmer complete the Stage 1+ package. The larger surface area of the aFe cone filters allows more air to enter the engine - creating more power and torque, a richer engine sound, and better throttle response. The kit is supplied complete with aFe Pro5R filters, mounting shield, intake tubes, sealing materials, hardware, and install instructions. The torque increase and sound from the open intake from low-mid RPM is sensational.

The Cobb software tool puts multiple tuning stages in the palm of your hand. Our Stage 1+ package lines up with the Cobb Stage 1 tuning maps for an intake and FMIC (91 or 93+ octane fuel). Simply download the Stage 1+ map from the Cobb website, plug it in, and install. Select different maps for other upgrades, throttle settings, octane ratings, valet mode, or revert back to stock! If you're moving up in Stages simply download a new file from the Cobb website and update your AccessPort programmer! The AccessPort triples as a diagnostic tester/reader and a data logger. It's the most feature-packed programmer on the market today.

We have taken the guesswork out of choosing the best upgrades for the N54 engine. If you follow the upgrade path we have laid out you will have very satisfying and reliable results. The addition of the larger intercooler makes Stage 1 more enjoyable and won't let you down at the track or dragstrip. * Note that peak power gains are quoted remain the same as Stage 1 but the cooler intake air means there is less of a chance the engine computer will cut power from heatsoak.
