I'm pretty sure or it wouldn't go in reverse right?? It pulls like a freight train then RPM fades out. Iv read that this could be a problem that some 2012-2014 have? The ECU is doing it because of engine lean spot
If you suspect the engine isn't getting enough fuel, then you can trick the air temp sensor to give it more or set the ECM back into break-in, whichever you find less intimidating. I run a wideband on my sleds, so any a/f or fuel delivery issues becomes apparent.
