i have a vmp tune for my supercharged mustang. Justin is one of the few that will tune for blown stangs via email and he has a big, big following with roush mustang owners and those using roush blowers. he also tunes the hell out of GT500's i know more people using his tunes than anyone else and everyone likes them.
I tried their tunes once when I was N/A, and Bamachips was having problems. Very pleased with it as it was; I asked them to make some adjustments to the shift points and got a VERY prompt reply with the adjusted tune, free of charge.
