Unknown_eyes started following 6.2 intake and TB on 2020 silverado 5.3. P0171 and P0174
I'm just curious if you've experienced and more CEL's or other issues. I'm thinking of doing this swap on my 2020 Sierra 5.3 and adding the Pulsar lt. I already have a gm cai and Borla S-type installed. The part numbers I've found are 12639087 for the l86 intake manifold and 12678223 for the throttle body. Are these the parts you used?
Drive a self tapping screw into the center cap with a cordless drill. Then use a pair of pliers to pull on the screw. They pop right off. But only if you aren't interested in keeping the old ones because they are now garbage! I did this when I swapped out for the black emblem caps. Zero damage to the wheel if your careful. Only takes a few minutes and your done!
I added the Range DFM disabler to my 2020 Sierra 5.3, 10 speed, 4x4. I had previously added a GM Performance CAI and Borla S-type exhaust. The exhaust just sounded strange when the dfm kicked in, so I got the disabler. The truck sounds alot better now, but my mpg dropped from 22 to 19 with the disabler.
I did the exact swap your talking about on my 2020 Sierra SLE. Replaced my stock 255/70r17 with a set of take off 275/60r20 with no ill effects other than the speedometer difference. My truck has the 3.23 gears, not sure if that would make any difference. My dealer did the tire size recalibration. I got lucky, the 275/60r20 was optional on my sle. They told me that GM would only authorize the recalibration if the new tire size was optional on your specific trim. The speedometer difference bothered me, that's the only reason I did the recalibration. If you can live with that then I doubt you'll have any issues.
It's interchangeable. Just a matter of getting the required parts and paint work. Here's some of the parts required not including the wiring, switch, and dealer programming to make them functional. I installed the gm accessory fog kit shown above on my sle. But used a harness from gen5diy.com that doesn't require dealer programming.
I had a cheap (less than $200) Tonno-Pro soft tri fold on my previous 18. I had intended it to be a short term option until I could get a nicer cover. I ended up keeping it on the truck for 2 years until I traded for my current 20. It was actually a nice tonneau and still looked new after 2 years.
The rear a/c vents on the console will work no problem as long as your current jumpseat has them. My truck also had the usb and charger port on the rear of the jumpseat with the a/c vents. So the ones on the rear of the console function as well. The interior console light also works. I simply unplugged the jumpseat harness and plugged in the console harness in its place. If your custom doesn't have this usb and charger port then it doesn't have the needed wiring harness to make the console ones functional.

Should be a direct bolt in. However that looks to be an AT4 with brown stitching on the lid. So you may want to change that and the side trim that matches the doors. If the price is good I'd snap it up. They are kinda difficult to come by. Be sure to get the trim finish panel that fits below the usb and dash outlet as well as the bracket on the bottom of the console. Also, I've read that if your truck is a base or custom then the wiring is not present to make the interior light or usb ports function without some custom wiring on your part.
