I have a problem with the RPM's when any of the tunes from the U7130 is installed on my truck. Here is the problem; When under a load, or not, the RPM's on the truck jump around above 1800 to the point where I am concerned that the truck isn't going to return to a standing idle. Anybody have an idea of what the issue is?

Try this:
options/troubleshooting/restore original backup, then reload the tunes.

Thanks

Tried that....even had the Engine ECM reflashed. It runs fine with stock settings.
