She's gotta sleep some time.
What did you do to your 2015-2020 K2XX Tahoe/Yukon Today?

Changed the fluid in both diffs and the transfer case. Each magnet had a little fuzz on it, not bad for around 30,000 miles since last change(s).
discovered that you can't flash a HMI with techline (sps2) that has built in nav to a vehicle that does not have nav, it just writes the HMI as no nav 
in my case I have on star nav only and ya so it didn't work.....
I guess the best you will get is to unlock the vin (not with sps2) with one that came from a same model vehicle or pay these business's hundreds of dollars that write them with custom files
***In my case you need a VCI number from techline to make it work

Filled up at Sheetz with regular 88. 15% ethanol and 88 octane. 3.09 a gallon I never see E85 or this regular 88 where I’m from. Bucees even had pumps for unleaded with no ethanol.

after a little web crawling I guess I need a VCI number from techline, which enables the functionality of the HMI as intended

Started the mods on my "new to me" 2015 Tahoe LTZ (build thread here). Swapped out the two front stock seats with two from a low mileage 2019 Yukon Denali. Replaced the worn console lid with an aftermarket one, and swapped the stock head unit with an Android tablet unit from AUCarAuto.

I decided to wait until it was 1pm and 101 degrees before I ventured outside to put my new Corsa exhaust on. I decided to be efficient and just sliced the stock exhaust in a couple of places to slide it out and it was the easiest exhaust I've ever removed or installed. The factory spherical clamp bolt snapped on me during disassembly so that added $44 bucks to the cost of the exhaust but luckily AutoZone had it in stock. I recommend removing the heat shield for the spare tire but I definitely wouldn't have gained anything from removing the tire like their instructions state.
After the chugging 4 bottles of water I decided to slap on the Hotchkis sway bar set. I left them both on the lighter setting and so far it drives how I imagined. I still really miss my old lowered Tahoe but it is that much closer now.
I am happy enough with the Hotchkis sway bars but I think they updated their hardware for cost savings without checking if it would actually work. The hex head bolts provided couldn't physically fit and be turned and the bushing brackets were not deburred well and all 4 required some file work to accept the bolts you can't even use. The instructions provided showed socket cap bolts which would not suffer from that problem and I was able to reuse my old sway bar bolts. As for the exhaust, Corsa 14826, I am pleased but it feels very quiet to me. My old Tahoe was lowered with TSP long tubes and Y pipe and it was aggressive as hell but wonderful and I guess I'm missing that. Perhaps more exhaust components will find their way onto the Denali this summer.

Drove it up to Banff, Canada. Checked out Lake Louis. Amazing stuff.
Hit and killed a bird on the way back to Idaho. It’s inside my grille and I’ll have to wait until I get home to Arizona to disassemble some parts to remove the dead bird.
