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.
