Ill be going with the 305/45R22 on my '21 Denali when the time comes, mainly for the slight size increase and the ability to keep a 4ply tire. Personally I would not run the previous generation trucks 285/45R22. Don't get sucked into the whole I want a lot of options thing if it really only comes down to you wanting an AT and not making sacrifice's.

Did you do a battery disconnect when you installed the new air intake? If you install the factory intake and the condition continues then you know it is not the intake itself. At this point cleaning the maf sensor on a whim is not suggested as you'll likely introduce another variable into this equation. Just my .02

vehicles have failures, if it's covered under warranty while you own it then who cares. You gotta live your life my friend.

My dealer said they are working on another update, but last I heard it still wasn't available. If they can make it start as fast as it used to that would be nice. But it hasn't failed me since first software update 10-18-2022.

On Nitrogen I'd see about 2psi swing cold to hot. Regular air will be slightly higher fluctuation like 4ish psi, but that is normal operation.

Not to overcomplicate this, But as long as you do not run below 41ish PSI you will not drop below factory weight carrying ability at any point. if you decide to go up, then that is your choice. I found my sweet spot at about 45psi.

I experienced the crank no start 2 weeks ago, took to dealer and dropped off same day. Got a call the next day for ECM update. Have not experienced it since. Crank time is definitely longer than before, but I thought these things always started up super quick anyway. If this is the resolution then I am happy. I cannot stand the idea of a cab-off surgery for the crank wheel issue on such a new truck.

I experienced the dreaded crank no start. Truck timed out, but then started right up on second try. Drove straight over to GMC dealer, found ECM update regarding crank no start. Have no experienced it again, but it does crank longer by default now. Just thought I would share for others that have read about the bent crank wheel issue some are experiencing. If this resolves it and no other symptoms come from it, I'm happy with this resolution. I just could NOT get on board with a cab-off surgery on such a new truck.

2wd models will likely get the G80 locker in higher trim models only. The truck you're describing seems like a rare combo, but a cool one. Welcome!

I did the first one myself at 5,500 miles a couple weeks ago. I did pickup 1mpg it seems using DexosD 0w20 and a upf66r filter

uggggh that interior tho

My local ACDelco / Motocraft suppliers have DexosD in stock. I have not seen the Mobil1 ESP X2 in stock anywhere. PF66 is getting low inventory right now but UPF66R still good availability.

There is a TSB for internal a/c condenser blockage with these, take to dealer.

my 21' works well in certain scenarios. If it's long straight highway it does very well. If it's winding 2 lane roads with the sun on the horizon, it will disable itself frequently. I figure at least it is smart enough to know it can't work correctly. I also like that you can adjust the distance for spacing between the car in front. I'm sure they are still working out some calibration settings, but overall I like it's features. But I do not consider this autopilot like others may.

Those tires need to be rotated twice as often as you all take them in for oil changes. 3-4k increments will be the only thing that makes them wear remotely even. They are great MUD tires. If I had a dollar for every time I saw someone complain about this and take one look at their tires and it tells this story.
