This is my second "drivability issue" post with my 2018 PW, 8K miles, all stock except for replacing the factory muffler with pipe. The truck acts the same with muffler installed. The following occurs with the truck empty, two occupants, not towing, cruise on. At low speeds, 25-50 the MDS kicks in and stays until acceleration is needed, in fact it will stay engaged under light acceleration depending on speed. Around 55 it will engage for 1/8-1/4 mile or so and without any throttle movement will disengage. In a bit, it will repeat this cycle. The faster you go the less it engages. I live in NW FL where most of my driving is on flat level roads. Just curious if this "excessive sensitivity" is across the board and considered "normal" in this truck. BTW thanks to all again figuring out my "Front End Noise"! STU
