I have the predator program in my 03 2500 6.0. I have the rev limiter set at 6000 and the first to second shift point at 5,800 rpm but the rev limiter is kicking in about 5650. Does anybody know why or what I can do?

Sounds like it didn't take the setting.

Is there anyway to cure this problem?

try re-programming it
