| I believe before you go either route Turbo or S/C you should test out your car on the track. The E46 M3 is an Amazing Platform to start out with on any track or road course. I would recommend doing a Hooked on Driving Event, Autocross Event or BMW Driving school to feel the characteristics of your vehicle on the track. Both F/I applications provide fantastic power.
