So I've owned the truck for about 3 weeks now.  I've changed the fuel filters, oil change, all fluids bumper to bumper are at the right levels. It has a stutter that I can't quite isolate. I don't think it's a fuel issue because it fires right up, never struggles to start. Happens when it's cold more but still can happen when it's at temperature. If I could take a stab at it I would think it's the throttle position sensor because it happens when you barely touch the throttle for the first little bit then if you get on it more it smooths out so I would think rather than being a smooth climb (if you were to graph it) it would have a gap at the bottom and then be smooth the rest of the way. Moparman1973 told me to unplug the quadzilla but I never got around to doing the whole procedure for that. Am I looking in the right direction or should I be looking somewhere else? Or is this normal? Thanks for your help in advance.

return the truck to stock first, unplug the Quad and see what happens.  Ensure when you unplug the quad you put the map wiring back to stock.

I'm not sure how pronounced your stutter is, but with my Quad on, if I manage to give just 1 or 2 percent throttle as slowly and lightly as possible, I get a bit of a stutter. I think it's the transition between stock program controlling idle fuel / timing, and the quad taking over. Probably the same reason I'll get a puff of smoke with the snap of the throttle no matter what I have the quad set to, even 50% valet mode. There is a bit of a delay before the quad takes control and cracks the whip on my big *** injectors.
