    Hey everyone first timer here not too sure how to navigate this site that well. My question: My 1996 ram 2500 Cummins doesn’t communicate with scan tools to diagnose anything. I even took it to a mechanic. I’d assume right off the bat that it’s my PCM or a wiring issue. I just installed a...

    Stuck in Limp Mode tried everything

    I am at my wits end. I have tried everything to get this truck out out limp mode. Drives fine at start up, then after you put a load on it, it kicks down into limp mode.

    Will pcm flash correct limp mode?

I had originally tried a diablosport predator 2 which put it into limp mode as it could not overwrite some of the exhaust codes. My question is if I return the truck to stock mode will a pcm flash get rid of...
