It's been a while since I've been on here. I had a nice engine build (550 lift cams , new pistons the works). And to male a long story short I paid the shop to fly cut my pistons and they didn't do it. Valves hit, pistons broke, cylinder walls were sliced and 7 grand went away like that. Anyways , I picked up a 99 cobra motor, computer, gauges and all the wiring for $1,500. Only has 51,000 miles on it. Everything works fine and all except the car has no power like it should. It falls flat on its face. Now I know the guy that had the motor before had a supercharger on it. He took it when they sold the motor. My question is if the computer is still programmed for the supercharger, would that cause it to have that large of a power loss ?
