I have a 02 GT M5 with a Procharger stage II w/ a 3 core intercooler. I will admit whe I first put it on I was a bit disapointed but when I started racing brand new vettes and leaving them in the dust I started to get cocky. I've had the sytem for about 5 months and haven't been beaten yet. So it is fast, the only problem I'm having now is that my intank fuel pump, (that's required when putting out over 400HP) bucks (bounces) under partial acceleration, it is very annoying and is really pissing me off, I also hear that vortec has better customer service, but thats just what I hear. I raced a 01 mustang GT with a vortec running 8lbs (same as me) and my car was faster. I don't know if I'm a better driver than the other guy or what, but I do hear that the procharger runs a little better. If I was you I would get a procharger running 8psi with the 3core intercooler. Omit the fuel pump they give you and save $185 then go out and buy the 2003 Cobra fuel pump, wich I hear won't buck like the one I have, you will probably have to get a custom chip because you are a 2002, Last time I check procharger didn't have anything for the 02s. Have the chip programed for 8psi like me, and when you feel like going out and really smoking some people slap on a 12psi pulley and pour in a few gallons of 100 octane and as long as its cool outside, my god, you will fly. I hope this helps, and I could also use some help with my intanke fuel pump issue, if anyone has a solution please let me know. Thanks a lot, and think before you race, there are some wreckles people out there. I could careless about you getting hurt, I just don't want to give the sport a bad rep. J/K
