This is what I have, fresh from the machine shop a 200K mile engine, bored 30K over, new pistons, rings, polished crank, RV cam, lifters, aftermarket heavy duty heads, H/O oil pump, headers. I kept the computer and the TBI carb and basically everything else is stock. The motor is assembled and runs good but would like to tune it. I'm finding it very difficult to find anyone that can re-program the computer chip in this year model, ANY HELP?? Also was wondering if a polished intake would help??
