Is there a stock bin for a 93 LT1 that can be used for a comparison against the bin on my chip. I know it has been modified, because the car has been modified. I would like to put it back stock and see what happens, am I way off with this? I have put the car back stock as far as I can tell. New cats and 02's tomorrow then I will do a datalog. Trying to pass CA smog. $DA3 is the xdf
