I sent in data logs as well.
I was also asked to return the truck to stock and send a gauge log.
I should have time to do that tomorrow.
The engineers are still trying to figure out what is going on.

Unfortunately, I still have the same issue; MM3 said the power steps on my truck could cause it, so I unplugged them a few weeks ago.
Didn't make a difference.
I'm starting to wonder if it was the new firmware MM3 released, as I didn't have any problems until shortly after updating the firmware.
This isn't very encouraging.
Any suggestions on a different tuner that I can purchase would be great.
If this can’t be resolved as a last resort, you could install a CSP5 switch to select tunes and an Edge Insight or Banks Idash to monitor PIDs.

I'm now being told the issue may be caused by the 12" Uconnect.

Same issue on my end with my RaceME.
I have a 2021 Cummins with the 12in UConnect, and all was fine up until about a month and a half ago.
PIDs read fine in the park, but as soon as you put the truck in gear, the PIDs start to bug out, reading "55," just like yours for current gear.
I can switch tunes fine, but the data on the screen is unusable.
The PID values will freeze up for a second or two and then flash a new value are all over the place.

The final results from MM3
"Hi Daniel,
Yes we have recently found out that unfortunately it is not something we can fix. I will explain. We have had some of the other trucks that have had it happen run some tests that allow us to pull data from the truck about what all the other systems in the can bus system on the truck are doing and basically what is happening is that there is another module in the truck that is requesting information across the can bus system. It is asking for the same information that the MM3 is trying to display for gauges. Anytime 2 different things request the same data from the can bus system on the truck at the same time it will cause glitches in that data and neither device will get consistent information. That is what causes the gauges on the MM3 to be glitchy.
Unfortunately the way this other module in the truck is requesting that info we can see that something is there and requesting it but we cannot tell which module in the truck it is that is doing it. Because of that we also cannot tell why the module in the truck has started doing this. It could be that whatever module it is needs a factory update, or it senses something a little off in the truck that it is trying to diagnose, or even something wrong with that module its self, or any number of other things but unfortunately with what is available to test there is no way for us to tell what computer in the truck is requesting that info.
Thank You"
