A friend of mine has a 94gt completely stock in good shape just needs a little interior work. He wants 3k for it and I really want to buy it. I have previously owned two 91 5.0's and one 96 cobra. I really liked my 91 because of the ECM accepting all of my bolt ons. I have heard that the 94 wont be as willing to accept add ons like a larger profile cam and exhaust because of the new emmission standards they started with OBD2 and all of that. My question I guess is what would I need to do to the ECM if I wanted to run an aftermarket off road H-pipe and supercharger ect... without getting poor drivability and check engine lights. Any help would be greatly appreciated
