HI I have a 2004 2500hd with lly. It has the edge juice with attitude magnaflow 4 inch exhaust and an AFE intake. When I lay into the throttle even on stage 1 I sometimes end up in limp mode. I know that there are a number of things that can cause this but I was under the impression that I would get a check engine light and I'm not. Should I just start with the fuel filter or is there something else going on.
