I had to revert to stock to do my emissions test, so I went into the RaceME Ultra and returned the truck to stock (along with the appropriate hardware).

While the truck drives like stock (duh!), I noticed a couple of things that were peculiar:

1. The exhaust brake will not stay latched to its last state after power cycling the truck.

I revert to off every time.

I distinctly remember this being latched when I had the RaceME tunes.

Did something not revert to stock correctly?

2. Rail pressure seems to rise on deceleration.

When the pedal is let off, the rail will go down to about 7k, but then rise to 26k in about 2 seconds, then drop back down to 7k.

This will continue until the torque converter unlocks when coming to a stop.

I quick search has yielded similar threads with no root cause, but again, I distinctly remember this never happens when the RaceME tunes were on the truck.
