My wife discovered we had not successfully resolved whatever the eff is causing limp mode. So sick of this damn thing.
I see that your sig says it is an 05. How late in the model year was it made? I know the 06 Silverado and Tahoe and the gmc counterparts and 07 classic Silverados, had a different wiring pattern and programming for the TAC module and TB. So if yours was late enough in the model year it is potentially possible that it got the same treatment. Symptoms of the wrong TB are reduced power warning once tps passes 50%, they seem to mask the issue until that point.
Or you have the 05 and earlier programming like it should have, and the TB is for a later model.
P.S. the plugs are the same, but pinned differently.

Thanks! That's really helpful. AFAIK, the pedal hasn't been looked at, though the throttle body, it's harness, and the connector on the Suburban have all been replaced. But the pedal ground and pedal sensor are interesting...
The gas pedal module is between the brake booster and the fender bolted up to the firewall

Replaced exhaust manifolds and most bolts with ARP or exhaust clamps, timing cover gasket, plug wires and FINALLY fixing the front end steering issue by moving the right side of the center link to the left side of the truck. Big shout out to @mattbta for helping me find the problem. Now the Denali steers like the Tahoe and not like it is stuck in 4WD.

Also had a man down, filter sensor got knocked off and forgotten about behind the tire.

I was actually considering getting those, as I have that SAME Air Dam on my truck. Good to know they fit perfectly in those squared off openings.
I was very surprised at how well they fit, just a couple washers and a splice into the wiring and you're good to go

I've seen the wiring pigtail at the throttle body have issues, usually the yellow wire breaks inside the insulation where the connector pin is crimped onto it. Will cause the truck to randomly go into limp mode. Best way to fix is buy a replacement pigtail and splice it in. I've fixed several of these with the same issue.

Considered buying this....Seriously though this poor eske didn't deserve this.

... between LOL and WTF...

Actually, if it weren't for the wacky paint job and maybe the wheels, the roof delete "mod" appears decently done. They even added a bed cap. Just don't get into a rollover crash, I guess? Or get caught in the rain? IDK
