Is there a chance these symptoms of trans re-learn or EGR not closed?

I did get one code during this test run that never appeared on the truck before.

I cleared the code and no change.

PO868Gov Pressure Sensor Volts too high.

I would say zero chance of a transmission re-learn causing your issues.

The EGR is a possibility that may be worth looking into.

I assume it is already electrically disconnected, so it should be normally closed.

If it ran well before tuning, it would have had to mechanically stuck open since then.

The only way I know to prove that would be to remove the EGR valve and check it’s closed.

If it isn’t, block the flow with a home made plate where the EGR valve attaches to the intake manifold.

If you can rule out the EGR and re-flashing the tunes, don’t fix the issues.

Check to make sure you didn’t unplug anything else after the truck ran fine.

Thanks for ruling out trans.

I was going stealth and told on my truck everything can remain plugged in.

I will dosconnect everything tomorrow tune to stock with deletes on charger and go from there.
