2008 6.7L Cummins - G56 Trans - Running Rough?

[AK Bob]

If anyone wanted to know what was happening, the rail pressure fluctuated at that rpm for some reason.

Tuner made that stop, and I don't have the issue anymore.

It's weird because he hasn't had to do that on anyone else's truck.

I wonder if I have a problem with my truck.

Thanks for the update.

Your fuel control actuator may be sticking intermittently if it starts happening again.

Please keep us posted.

It's been a while, LOL, but we figured it out.

For some reason, the MM3/RaceME software has mislabeled parameters related to the emissions system.

I turned these things back on, and the truck runs perfectly now.

This is a thing only on G56 trucks.

Weird.
