Our M5/M6 Stage1 tune has quickly become the gold standard in //M performance, reliability, and value. It installs and removes quickly, provides reliable 30-50whp/40-60wtq gains. Unlike some of our competitors the BMS Stage1 tune is compatible with both base and competition flash vehicles. Drives as smooth as stock only with a lot more power available when you mash the pedal.
Note we've adjusted the Stage1 tune so that special setting changes for the M5/M6 are no longer required. In addition we've removed the option to adjust the boost levels. Boost is fixed at a maximum of +4psi over stock. For higher power levels or heavily modified vehicles checkout our new s63tu JB4 system.
