Adding a TMS Performance Chip gives you the biggest bang for your buck! Jim Conforti tuned these chips on the dyno to boost mid range torque and increase horsepower in the upper RPM range. Where the stock V8 seems to fall flat above 5500 RPM, the adjusted fuel and spark maps deliver more horsepower to keep the engine pulling all the way up to the new 7000 RPM rev limit. The best thing is that there is NO downside to installing a TMS Performance Chip. Turner Motorsport has been in the BMW chip business for close to 10 years and all chips are dyno-tuned to achieve optimum performance and safety. As an added feature, the top speed limiter is removed. Premium 91+ octane fuel is required.

We need to know the ECU numbers, transmission type, and production date of your car. Please enter this information into the Comments section of the Order Confirmation Page on checkout.
