I've done a search and read the results, but didn't find anything useful.

2020, not deleted, 76k miles. 37s, speedometer corrected with Alfa OBD. BMP Cat filter conversion front & rear since 36k, and HSS EDT since new. I drive conservatively and don't beat on the truck.

Truck has begun having an intermittent stutter or shudder while driving. It happens when lightly accelerating with no load, approx 50mph. When it first began I could barely tell and initially thought it was the road. Lately it has become MUCH more pronounced. It's difficult to tell if it's the engine cutting out or the transmission causing the issue. I've changed fuel filters and filled up at a different station.

No WIF light (I have both sensors in the factory locations), and no CEL.

Any thoughts or ideas what could be contributing to the hesitation while driving? Dirty MAF sensor?

What is the CP4 recall as this sounds very similar to the issues I am having. Same mph and similar mileage on the truck. Mine is a 21 though.
There was a TSB for this.

The CP4 recall was performed and new firmware install

CP4 recall was only for 19-20 trucks that had a CP4.2 HPFP.

21+ trucks have a redesigned CP3 (CP-ISB21).

When was the last time your fuel filters were serviced? Ensure you're using only OEM filters not bought from amazon or ebay.
