Just a follow up on my previous post. My 2017 now has 78k miles. I had the spark plugs changed cleaned fuel injectors and had the mechanic put a scope into two cylinders to see the tops of the valves. Spotless. Zero carbon! I have always run 92/93 octane and use full synthetic oil since new. No holes drilled, the engine purrs like a kitten and moves (when I need it to) like a cheetah when I need it to. 3.73 rear end gives me faster off the line quickness vs 3.21 trans. Towing? Smooth, plenty of power, handles the 9000 lbs I put on it a few years ago.
