I have a bluefin (superchips) map on mine and am not happy with it as i know i can get more power, so tomorrow i am going to revo HQ to get it remapped by them....
Do a search mate there are loads of threads about remap companies... custom code, revo, superchips, p torque, GIAC.... all have there ups and downs... most repsected i would say on here is revo.
