Tuning a car that is an already hot-rodded version of the M3 (M3 Competition) still yields plenty of gains; despite the healthy stock baseline.
New OFT Stg1 v2.2 tunes are killer. Smooth, progressive and powerful!
Thank you to Christopher Evan Lam for allowing us to use his car for additional testing for the greater good! This car is still 100% stock hardware with ONLY an ECU tune -> SMOG COMPLIANT!
