We have tuned this engine in many cars from the small nimble M2 comp to the track orientated M4 cs. Carrying out Stage 1 tuning all the way to fire spitting hybrid turbo and water methanol fuelled combinations. 



Stage 1 remap requires no physical changes to be made to the car this is software only and sees a huge gain in performance from standard power.


Stage 2 remap requires as a minimum decat exhaust, some replace charge pipes for harder than stock as they are prone to breaking and there is options to upgrade the charge cooler itself
