John,
As I mentioned to Greg, try running the truck in "stock" mode for an hour or so and then retry the performance program. Sometimes the PCM learns a bit far in one direction and needs some time to settle back in to a "normal" type of mode.
If this doesn't work, I'm certainly happy to revisit the calibration and make any adjustments necessary.
Keep me posted.

Bring back  Windows™ XP and 7.
 Windows™ Vista and  Windows™ 8 is a pain in my a$$!
 Windows™ 10 is only slightly less annoying!
 Windows™ 11 is garbage!
Much to my surprise, I'm actually quite enjoying Linux!
