Awesome. I will try this stuff out and report back

Isnt the W/T mod for automatic trucks?

I thought APPS almost always set a code? The truck never runs completely away, just spikes RPM for a second and comes back down.

Hey guys so this pretty much all happened about a year ago, I was cruising home ( nothing crazy) when all of the sudden the truck started surging and gaining MPH/RPM. Limped it home it would just randomly spike RPM to redline sporadically and come down to idle. changed fuel filter and seperator (FASS) and found my FASS had a popped fuse, fixed that. 16 PSI of fuel pressure, no CEL and issue still occured. Put a scan tool on it and the scope showed spike in voltage on ECM, APPS, and VP while the RPM jump was happening. Im leaning towards replacing the ECM. The truck has been off the road for nearly a year now from this and really want to get it back running. Has anyone run into an issue like this???
