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.

This software is a reflash of your computer. The computer will need to be sent to Turner Motorsport for the installation. Click here for specific instructions on shipping the computer.
