so guys i have a 99ss Camaro, just swapped in a stock 2000 corvette ls1. Car has full exhaust and a kn fipk and 80mm bbk throttle body. I just did new plugs and wires. Let the car run, hooked up my scanner no misfires at all as its running but runs rough. All the ground are tight. I double checked everything. The computer in the car was tuned by frost when it has the original engine with a ms4 cam so the car is running with a computer that's tuned for a cam but idk if that would do it. Any help much appreciated

most likely running rough because its looking for the timing and fuel curves that was needed to run an MS4


did you have bigger injectors on the old engine?

im thinking its most likely the computer since its more likely getting more fuel than it needs. the timing also will be off as well.

I didn't have bigger injectors I had a ms4 cam, ls6 intake and tb. Now I have stock motor stock ls1 intake and 80mm throttle body

need to have the computer re-tuned

quick fix would be to find a stock computer and swap it in

Or have frost flash a stock tune back in
