Thats what I like to hear..lol. He said normal driving your fine and it will idle, and he said it seems like it would want to go when you sort of get into it, but it hesitates alot.
As far as trans settings, better to keep with a GTP PCM im assuming and just flash those into there? Also, will he GT trans. hold up ok or would a GTP trans swap be a good thing to look into?
Dont swap a Factory trans. Look into a Triple edge trans or build your own.
