I have noticed this when I have been n the carpool line. The really odd thing is that it (the time) updates periodically, but it’s been difficult to tell when it happens. Even though it updates, it’s certainly not real time, and even after it updates, its behind until I start the truck.

I just had the performance exhaust placed on my 6.2 AT4 yesterday. Love it. Did not do CAI. I just couldn’t find anything that definitively said it was worth the money. I’m not opposed to doing it (or maybe one of the other aftermarkets) in the future if it will improve performance/ mpg’s. The exhaust itself did everything I wanted it to for the sound.

Schmoe posted a topic in 2019 Engine, Driveline, & ExhuastI’ve seen it asked in a couple of threads, but haven’t seen any answers. For those who have changed to the performance exhaust after purchase, what are you doing with your old exhaust? Only answer I have seen is “save it until I sell it”, but I have no interest in that. Just take it in for the scrap metal? Let dealership dispose of it? Has to be worth something at a scrap yard, doesn’t it?
I ran ko2’s 285/55 (maybe 60- can’t remember for sure)/20’s on 2015. Just ran them at 35 psi, but rotated 5k religiously. Sold with 92 k miles (tires had 89k) and they still had a ton of life left. But they did have a terrible Chevy shake 70-80 mph that I couldn’t get rid of. Now running 275/70/ 18 on a 19 at4.. My question is this; Ive got 48 psi front, 38 in rear. Unbelievably smooth. Why is the manufacturer recommendation having the same psi in the front and rear, when, per their own specs, the curb weights are significantly different in the front and rear? Doesn’t it make since to increase psi on the heavier part of the truck (assuming I’m not hauling anything)?
