computer options? please help
ok ive got a classic fast in my 98GT (4v swapped turbo car) the car just runns like poop, it has erratic idle and you cant drive it normal, its either you gotta be on it or not ect. it also will randomly cut off if you stop too fast or sitting at a stop light
now here is the question... do i swap the classic fast out for a XFI system, or go back to the stock setup and put a chip in the computer?
anyone have experience with the XFI vs CLASSIC fast? id kind of just like to have ppls thoughts on this
also this is a street car too
98GT.... little this a lil that
