Here's to reviving an old thread. I did this exact setup this weekend. Went fairly smooth and all went together good. Only hickup I had was the rear cut is super close to the hanger so there isn't much room to get the clamp on. Had to do a little tweaking to get it all lined up but overall went well. I like the sound...not overly loud but can tell there is still something more than stock there. No drone noticed on the way into work this morning. Curious to see how it'll sound pulling the camper. Thanks to the OP for this write-up.

It didn't extend the remote start time...just keeps it from turning off automatically after you start it manually. I went to Graff...GM gave them a hard time about getting the programming not only for me but a buddy of mine whos also on the fire dept with me.

Any updates? Super curious how this worked out....

On a slightly unrelated note, where abouts in MI are you? I'm about 10 minutes East of Flint....

Any updates on this yet? Very interested to get your thoughts...especially with that pricing.

I have the blue ones on mine. No complaints so far. I did not install the 1" spacers on mine. It does help a little with sag when hooked to our camper but I can def notice a difference in the ride with the camper hooked up...our weights are about the same as yours. Don't even notice them there when unloaded...no severe shock to the truck when going over bumps or anything either.

Continental TerrainContact A/T's are supposed to be really good also. No personal experience with them yet but I'm planning on making them my next set of tires. I don't take the truck off road very much at all but I want something that's functional year round here in Michigan. Also I pull our travel trailer so need something with decent sidewalls...I'm past the point in my life of looks over performance with tires.

For you guys that have already bought/installed these, are you going with the fog or driving optics? And sport or pro power level? Not sure what I want yet so looking for some feedback.

I don't do anything special to keep it running. Start the truck via the pushbutton, when I get out I lock it with the fob, and it stays running. If I use the remote start, I start it, let it run for a bit, push the pushbutton, and continue on. Not sure what's going on with your truck sir...

There is another thread with some more info on this here:

I don't believe so(I could be wrong seeing as I don't have one) but I suppose that is a possibility. I had a buddy that had a 19 custom and his didn't time out after an hour but knowing GM, they could have changed the BCM programming lol

So with the key, the vehicle will run after you put it in park until you shut it off. If you have the "push to start" button, then from the factory the vehicle will idle after you put it in park for 30 minutes with the keyless fob out of the vehicle and 1 hour with the fob in the vehicle then it shuts off. This programming removes the idle time-out feature the vehicle came with so it only shuts off if the button is pushed....or it runs out of fuel...which ever comes first.

I had to go twice because the first visit, the dealer did TSB 21-NA-228 at my direction but the programming for that didn't work in my truck. When I went yesterday, they did 21-NA-056 and the programming for that one did work. If I would have known about 056 the first time, I wouldn't have had to go twice.

I've noticed on Maps+ that it routes weird sometimes. It has wanted me to get off the freeway and go around in spots when Waze shows staying on the freeway and no issues. I thought it would be convenient to have it on the radio without having to plug my phone in but I find myself using Waze almost exclusively for navigation now. Maps+ def needs some updating and refinement still.

The first time I went, the dealer only charged me labor which was $75. This time there was a charge from GM for the programming files and that was $100 but they didn't charge me labor for it so I'm in for $175 total.
