i wanna install the ls1 throttle body on my 97 gtp, and bluegtp91 gave me a quick run down on the chat that pretty much i need a tb adapter plate, flipped throttle bracket, external maf, and tune. where would i be able to get one of these adapter plates from or have made and also would a pcm like one from zzp or overkill or something be able to accomodate for that or would i have to send my pcm to have it tuned?
