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

You don’t like headrests?

I pull them out when I am working in the truck so I can reach around the seats easier.

Been meaning to change the serpentine belt since we bought this 30k miles ago now, woops. Got 2 of the kids involved and changed belt (appears I got the St patty's day version lol), tensioner (painted up quite nice), and idler pulley over the weekend.

Having different colors for each side actually makes it easier when you are routing the belt since both sides of the belt run various accessories.
I like it.

Installed that pre cut tint. They were cut to fit very well. I highly recommend. Only bump on the road was the brow tint didn’t have the mirror mount cut out so I had to trim that part.

I didn't pay attention to that but this is actually a good point

Pulled the pillar cover off and can't find anything or under the end cap of the wipers that could be leaking. Looks like they changed the sunroof drain design the hose in mine is one piece there is no connector under the pillar. I'll have to pull the wiper arms and cowl off and look down that way

Wasnt today but last weekend concluded a 2000 mile round trip adventure from the Midwest to the Gulf Coast and back. Tahoe did just lovely with the drive and 5 people in it. Still managed to keep the luggage low enough to see out of all the windows

'Finished' installing driver side H3 motor mount! Original was torn all the way across.
Next week maybe I'll get to the passenger side..

Updated my transmission tune with shift points from a 2015 tahoe (3.08).

Noticed the PPV 2015 Tahoe has earlier shift points than regular 2015 tahoes by 1-2 mph in most areas (assuming it is for smaller tires).
Some areas of my stock map were 1-2 mph higher than the stock 2015 tune, so I kept the highest numbers and blended slightly.
BUT the raised downshift speeds really help minimize lag. (and was more aggressive than my current 'cruise' tune)

I'm sure you can get even more aggressive, but this is basically a 'factory' 2015 tune above 20% throttle.
0%-20% I have it bumped 4mph over stock 2015 for 2-3 and 3-4, 3mph and 7mph bump when compared to stock '12 tune.
That's just to keep it in gear as long as possible, without noticeable engine braking after shifting.

Also the 2015 has a WOT shift RPM of 5,600 RPMS in all gears, so I bumped some of mine up from 5,200.
Plan to update the tow mode tables before too long..
