It lists for $1200 and change. I don't expect to get that, but I would like $800. The brand is AuCar, and the screen measures 15.6". Here are some links regarding the unit: https://aucarauto.com/product/aucar-tesla-android-13-15-6-car-radio-for-gmc-sierra-chevrolet-silverado-2019-2024/

I have one for sale if you are looking to purchase one of the T-style units for a 2019-2022 AT4/Denali. I did not get a chance to install it before I moved on from the truck.

I have one available for sale if anyone in the VA/NC/SC area is interested in purchasing one of the T-style units for their 2019-2022 AT4/Denali. I did not get a chance to install it before I moved on from the truck. Let me know if anyone is interested.

Update: You no longer have to send the ECM to the company for unlocking. They sell the FlashPaq with Locksmith device, which allows you to unlock everything in your garage using the hand tuner and update software via your personal computer. The new system (2849-F) allows you to unlock the TCM previously unavailable on the older FlashPaq tuner for the 19-22 Sierras. This is great because, depending on what tune you used, some of the shift points would be a little off (surge/holding high RPMs when not accelerating). I have reached out to Superchips to see if there will be a kit/software update for those of us with the older FlashPaq (2847-S) so we can benefit from unlocking the TCM and correcting some of the shift issues. website: https://www.holley.com/products/tuners_and_programmers/handheld_tuners/superchips_f5_flashpaq/gm_flashpaq_with_locksmith/parts/2849-F website: https://www.americantrucks.com/superchips-sierra1500-flashpaq-f5-tuner-locksmith-2849-f.html

Update: The GM color for the AT4 steering wheel and infotainment trim appears to be called "Vulcan." However, I am having difficulty finding something similar from the known vinyl distributors. I attempted some sample pieces from Rvinyl (Brushed Aluminum—Gunmetal; on the right and darker than the picture shows) and Metro Styling (Brushed Steel Metallic—too bright/silver/shiny). I ordered a black brushed aluminum sample from Rvinyl, so I'll see if that is any closer to "Vulcan" than the gunmetal.

Does anyone know what color the trim piece around the infotainment system/steering wheel is called? It appears to be brushed aluminum, but is it gray, gunmetal, or black? I am about to pull the trigger on the T-style 15" screen upgrade, but the trim piece with the kit looks like it is for Denali/LTZ/High Country trims. I intend to wrap it to match the steering wheel as closely as possible. I am also going to wrap the door/console trim. I'm not a huge fan of GM's carbon fiber-like look.

The performance tune has a modest HP/TQ gain in addition to the throttle sensitivity. The "performance" tune is more HP than TQ, while the "haul" tune is TQ-focused. The power increase is not as drastic as the numbers you are going to see with the 6.2 (which are the numbers they advertise), but I have no issues with get-up-and-go running a lift and 35s while doing truck things. For the 5.3, it definitely increased the joy of driving and seat-of-the-pants performance. It is important to note the "performance" tune is not for hauling, but with the ease of switching tunes, it is not a terrible headache to switch when I need to haul something (which is not very often and planned well in advance). Yeah, you have to send the ECM to the company (Holley is the parent company, I believe) to have it unlocked to work with the handheld flash tuner. It was about a 72-hour turnaround. My only concern now is whether or not I am able to add a supercharger since another company unlocked the ECM. I am going to send inquiry emails to tech support at Magnuson and Whipple to see if I can use my current ECM or if I need to get a new one for the supercharger tuning.

Matt, I have the Superchips Flashpaq. I ran the 87 tune for one tank, and I will tell you it is not worth it. The tunes will not affect emissions, but if you are considering using it for towing, use the "tow tune" and run the higher octane fuel. The 87 tune will likely not get you the performance you want. For context: I have a 2021 GMC Sierra AT4 with a 5.3 10 speed. Exceptions - I am running a Fabtech 4" lift, 35x12.5x20 Toyo AT3 tires, Cold Air Inductions CAI, and the Borla S-type exhaust. Flashpaq bonuses: the button memory is great; it disables all the silly things you don't want a V8 to have. The calibration for tire size is pretty much spot-on. The pedal sensitivity adjustment is enjoyable, but it can decrease fuel economy due to the fun of it all. My "real world" numbers on 93-octane and the performance tune: average of 425 miles to empty on fill up; 17-18.5 mpg by hand and on the computer (400-mile distance calculation), and incredibly fun to drive. Respectfully, Doug
