S63 TU Stage 1 ECU Tune for 2013–2016 BMW M5, M6, X5M, and X6M

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 on pump fuels, and up to 80whp/100wtq gains on racing fuels with more heavily modified vehicles. The BMS Stage1 holds the M5 1/4 mile drag racing record at 11.0@128mph and the 60mph-130mph record at 7.1s. 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 the BMS DATA cable is required to enter M5/M6 specific settings during installation.
