What did you do to your NNBS GMT900 Tahoe/Yukon Today?

[iamdub]

5,000-mile service (oil change and tire rotation). Had the girls clean the wheels for a little spending money while I had them off. Blew the dust out of the brakes and some other little stuff that I'm not gonna mention until I see if it made it any difference.

Oil life monitor was at 50% and the oil looked really clean on the dipstick. Only slightly darker than new:




Jenn's been the primary driver so it's had maybe 5 WOT events during the few times I drove it over the past 5K miles. There was almost 3 times as much oil in the catch can as last time- proof to me that the AFM system contributes more to oil consumption than high-RPM:

Got the TruCool I stalled today.

Got my SLP resonator delete and Magnaflow muffler installed



Fully TIG welded

Still might bring the tip closer to the body, waiting for new hangers before I made further adjustments...

Another thing I need to add to my "I need" list.

Well... No life in AC anymore. Just the three blinks of the light on the AC button. Belt is still on and clutch and pulley still turn easily.

Gave up and took it to the only shop in town I trust to touch my vehicles if ever needed. Let's see what the verdict is tomorrow. Mentally already preparing myself for a four figure estimate... Uggghhhhh.........
