I vote 295/60r20, they look wider than a 275 or 285. Im running 35x12.5r20s on 20x10 wheels on my 21 TB with a 1.5" spacer. I had to do some modifications in the fender but it looks very clean.

Thanks for the info guys, If the gm branded intake comes or does require a MAF recalibration im pretty sure thats what im getting. Im sure it just widens the bandwidth for the sensor. I may reach out to the service writer and see if he can help me out with this, its mostly annoying having the check engine light on since it wont let me remote start... I do plan to get a tune done to it soon, anyone know if doing this would change this?

I did the muffler delete pipe from AFE, i enjoyed it but the wife said it was too loud. I left the flap in place when i installed it to help at low idle and cruise. We also bought the AFE muffler kit for her 21 escalade but after a few months she wanted to go back to stock so i now have her AFE muffler on my truck with the flap removed. Its still pretty loud but while cruising its pretty quiet. Side note the 21 escalades have a flap before and after muffler, which makes there exhaust alot quieter. I removed the one behind the muffler when i put the factory muffler back on to just see if it made a difference in sound and it unfortunately didnt.

Hey guys ive got a 21 trailboss with the 6.2l with just over 13k miles. Right after i bought the truck i add a volant cold air intake and deleted the muffler. After a thousand miles or so i would get a check engine light that would come off and on (soft code). A few months and a couple thousand miles later it starts to idle rough and eventually start stalling at stops. So i had my father inlaw check my codes and it had the po171/po174 (fuel trim system lean). Also had a PO106 and P16F3. I took my truck to the dealer after this and said it needed a new ECU which they replaced under warranty. The service writer said with the intake i will likely always have the PO171/PO174, but the stalling will stop. A couple days later after the new ECU my check engine light came back on. It sometimes idles rough at stops but has not stalled again. My question is anyone else have these issues after adding a cold air intake? Ive had quite a few vehicles with cold air intakes and never had this issue before which leads me to believe something else is causing. Wanted to pick some of yalls brains before bringing it back to the dealer to have them dig deeper into it. Figured as you can buy a performace package from GM with cold air intake and exhaust would lead me to believe it should run fine without a tune.
