please help!!

 

Possibly, the programmer and the cam aren't agreeing. I don't know what to tell you to do other than mess with the programmer.

You need to see what you are getting for knock retard,How does it feel at 1/2 throttle compared to before?Did you put on Ls1 heads? compression?what cam?
