  1. 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
  2. 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.
  3. 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.
  4. 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.
  5. 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.
  6. Morning all...I had the dealer do the above TSB(21-NA-056) and I can confirm it worked. I did have to pay for the program from GM and apparently GM Tech gave the dealer somewhat of a hard time about getting it but they were able to get GM to give it to them. Just thought i'd give an update for anyone debating on doing this.
  7. So i had this TSB completed on my truck last Monday...much to my disappointment, it didn't work. I reached on one of the FB groups, and someone posted this TSB that they said worked. I'm going to contact my dealer and see if they can give this one a try. Just as a heads up for anyone else looking to do this.
  8. I've been debating purchasing this also...not much out there on it. Searched YT also and nothing...
  9. Def going to be looking into this ASAP. I go direct to calls from time to time at my fire department and being able to not have to worry about the truck shutting off while on the side of the road which in turn kicks off my lights, would be great. Plus on those cold days, truck stays warm while we are out.
  10. I have the blue sumos and bilstein's on the rear. The bilstein's def improved the ride by themselves. We have a travel trailer close to the same weight as the OP and I notice a difference when pulling the trailer for sure. The sumos help with the slight bounce we had...no noticeable difference in ride quality when unloaded(maybe on some super harsh bumps...thanks MI roads). Of course a properly setup WDH hitch also helps with the bounce. Overall...very happy with our setup.
  11. Morning all. Just curious if anyone has any experience with the above stated exhaust system. It replaces just the section from flapper to flapper and has a built in J-Resonator. Thinking it might be a happy medium between a full exhaust and a muffler delete(which I currently have). https://www.magnaflow.com/products/19534-performance-exhaust-magnaflow-d-fit-muffler-replacement-with-muffler-performance-exhaust-system
  12. Mine does it also. Come to think of it, the last couple trucks I've had did this. I'm so used to it now that it doesn't bother me anymore lol
  13. 93 since the day I took delivery...for the extra money I spent to get the 6.2, running 93 isn't that big of an issue.
