i've got an 04 gtp compG.
i've read posts that bagged on the canned tuned PCMs. however, now that i think about it they may have been baggin on zzperformance's canned tuned PCMs. alright man, i'll look into 3800 perf's PCMs. i've got nowhere to go but up with my modding...

Thanks for the advice bluegtp01!
