What did you do to your 2015-2020 K2XX Tahoe/Yukon Today?

[Congtoid]

I walnut blasted the intake valves and did a 6.2 intake manifold swap on my 2016 5.3 Yuki.
Will make a separate post soon.

Installed a Diablosport Intune I3. The reviews I saw on the internet really undersold how much this tuner transforms the truck. Drives how it should now. Compared to a Cobb Accessport on a turbo Subaru, the difference the intune made was extremely drastic (in a good way)

Flushed coolant a bunch of times. went through 12 gallons of distilled water. After that, my son changed the tensioner and belt. He looked up the torque specs, set the torque wrench, everything!

Also...a little test fit and function test....

I tried to data log for my BB tune today and my autocal won’t data log for some reason. I messaged BB so it will be a day or so before I get a SZ response. Definitely miss the old in person tunes. Would have been had this done if that was the case. I imagine due to the errors and only being able to play around with this every other weekend, this will be a long drawn out process. Couldn’t retrieve current tune either as message indicates “file system full”. I just check the trans fluid, changed my air and cabin filters to make it feel like I got something done this weekend I guess it’s pinkish

Changed rear brakes. 103k on the original brakes.

Today I'll be diagnosing the front clunks I hear from either side (though not at the same time) during a slow body roll. It started with the new sway bar and end links I installed. I've been tightening them bit by bit, but in the directions they say there should be 2 or 3 threads showing and I have something around 10. I did just find a Moog video that says 14 ft pounds so I'll open with that and see. If that gets fixed, back to the head rest install.

Edit: Turns out I have a bad wheel bearing. Yay. At least the weather is nice.

Took my 'Burb to the dealer this morning to address a squeaky sound that happens during road imperfections on the highway. Crossing my fingers that it means something needs to be lubed.

I posted my outside rearview mirrors and premier center console in the For Sale section.
