My brothers pickup
2015 Ram 3500 SRW mega cab, 6.7 cummins with the Asian trans. 40,000 miles
Raceme ultra and flo pro exhaust race pipe. Flo pro block off gaskets for egr. nothing else aftermarket on the truck, all stock.

First 35,000 was all stock, non deleted and not 1 issue or hiccup.

Deleted it in June of this year and has 5,000 miles on it now since and it has always done this periodically.

While idling, the truck will miss once and the pre heat message come up and ding. 3 times its stopped the engine to 0 rpm, fires right back up and is fine. But most of the time it just skips and the message comes up and then it idles like normal. Sometimes it will puff a little blue smoke.
No codes either.

We have used a trickle charger while re flashing, but also re flashed when truck has been driven and is nice and charged up. We turn everything off lights and such and make sure there is nothing plugged in to the usb or 12 volt outlet while it gets flashed so I don’t think it’s with that.

We also have tried leaving the egr stuff plugged in and not plugged in and it still does it.

His tuner is up to date with the latest updates.

Also the truck was first tuned with stock everything with deletes but it would just at random times the throttle would not work, the truck would just idle, you would have to unhook the battery’s or re flash it. So that’s when we tried different power settings on the raceme.
