Truck sputtering when I accelerate in 6th gear
I'm new here and this is my first tuned diesel. Bought it used with 62K miles on it. So my question: my pickup is a 2012 Cummins 3500 with a 6spd manual. It has a H&S Mini Maxx chip on it with a Sinister Diesel EGR delete on it. As far as performance part on the motor, tranny and clutch I have no idea what's been done. If anything at all. When I turn the tuner up to street or performance mode it's in the sixth gear and I give it full acceleration, the truck kind of slips, or stutters. It'll be fine in all the other gears though. It'll keep accelerating in the sixth gear but nit without kind of stuttering. My guess is it's too much power and the clutch is slipping but I'm not sure. Anyone with any ideas??

When was the last time the fuel filter was changed? My truck acts in a similar way when the fuel filter starts clogging up and the lift pump fuel pressure drops to the CP3.

Not sure, I just got the truck 10 days ago

Filters and fluids would be a good place to start regardless, at 62k they are right on schedule to be replaced. Check the owner's manual.
