Guys, i would highly recommend Evolve if you want to go the remap route. I;ve had 4 M3's now, 2X 3.0L and on my 2nd Evo saloon and had them as well as other cars mapped by other tuners but this remap that evolve do is head and shoulders above the others. I've done a review in this section. They are sponsors on the M3cutters forum and a lot on the forum have their remaps so you can read reviews and feedback there. Absolutely awesome all round, not just top end. Torque has increased throughout as well as BHP and even littel inputs of throttle can be felt.
