think about try the SCT tuner, it works really great. i have it in mine and haven't had any problems. its to my knowledge that its actually using the stage one programing with a little more tune to it. i think there are some others that have used it on here. and i know for sure that over at ptcrew there are plenty of people that use it. theres a guy over there that is selling it too. pretty cheap i must say. the only downfall is get a speeding ticket!
