2019 Yukon Build

After that, came the Denali cluster swap:

The problem (in my opinion) with the Denali cluster is that you lose the ability to check the transmission temperature, and oil pressure.

Looks like you are making quick progress on a fun project.

If you change your display to the 4 mini gauges then press the trailer/tow button it replaces the voltage gauge with trans temp so you can see both oil pressure & trans temp. Pics are from my 2018 Yukon Denali.

I installed a BellTech 2/3 drop & Hellwig swaybars on my 2018 and the improvement in handle was incredible. Changing to 305/40/22 General UHP tires improved it even more. Both my son & I had AFM lifter failures. I did the AFM delete via a cam swap 25K miles ago so now I have peace of mind that I won't be stranded far from home with a lifter failure.

My next upgrade is 16.25" rotors in front with 6 piston Brembos & 4 piston Brembos in the rear. Just received all my parts this week.

I saw the 4 smaller gauges, but I like the technology theme better...or it could be that I don't want it to look like the stock cluster at all, haha. AFM delete (as opposed to disable, like I have now) will be in the future, for sure. It'll most likely be next summer...and knowing me it'll be a head upgrade and cam swap. I'd hate to do all that work twice (is how I justify the heads to the wife). Over the winter my son and I will be building out a 4R70W I have for my 1989 F150 that is an ongoing project (86k original miles, built 351w, all that fun stuff). Once that is installed and running good, I'll feel comfortable taking the Yukon down for the DOD delete.

You mentioned 4 piston rear brakes...Do those come on the 21+ PPV Tahoes, too?

I'm going to use Gen 6 Camaro rear Brembo Calipers on my Yukon.

I did the cam/lifter swap last year and was able to walk off then back on the timing chain with very little effort so didn't have to drop the oil pan. 1st swap I did took 20hrs, 2nd time I did it in 15hrs. Time consuming but not hard.

My son and I went for a bit of a road trip to buy a GPI ported 6.2L intake and TB today, just over 400 miles round trip. Turns out the guy works at GPI, and was telling me about their ported heads, tuning, etc. I might go their route whenever I end up swapping the cam, I'll need to look into them a bit more. I'm very impressed with the gas mileage I got, the 400 mile average is 21.1 MPG. The roads are very hilly and curvy between AR and MO, and it was foggy\raining the entire time so road conditions were far from ideal. Either way, it was a great trip, and the Yukon did great. Intake install might be tomorrow, might be next weekend. Pics will be taken, but here's the intake as we bought it:

My son and I installed the intake today. We were not the first people in there, the harness was already disconnected from the back of the plenum cover, and the foam is not placed under the plenum cover correctly. The install went very smooth, and the Yukon adapted to the larger TB and intake nicely. The biggest difference I've noticed is the sound, but there is a power difference, as well. Before, the CAI's throaty sound was abruptly ramped up around 1,800-2K RPM whereas now, it's a more gradual change starting around 1,300RPM. There was a power gain, mainly in the low and mid-range...about on par with what the CAI did. Intake runners were a bit on the dirty side, but we were limited on daylight so that'll be another day's project. The catch can should prevent them from getting any worse. Here's some install and comparison pics:
