This is my THIRD "drivability issue" post with my 2018 PW, 9K 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. My concern is with the automatic forced downshift especially with cruise on. on a flat road ( I-10) at 70 or above when a rise is encountered ( an overpass, bridge ) a downshift is forced only momentarily then up-shift. It feels like there was plenty of power and only slight acceleration should have been needed. If a long slope is encountered it will downshift then upshift as above but will go thru several cycles while ascending the rise. at slower speeds (60) on the I- 10 scenario it is not as prone to downshift. I would think at 70 with the rpm near 2K I would have more power than at 60 around 1600 RPM but of course have no idea what the VVT is up to. The only load difference I can think of is higher wind resistance above 60... but that much? I had it at the dealership in June, they were contacting FCA. Is this too "normal"? STU
