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

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.

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..
stock 2012 tahoe tune / modified+2015 tune
changes to stock 2012 map.

Do you know what you averaged for mileage? I did the same trip last November, WI to AL on a stock 5.3 and was right at 16 mpg for the entire trip. First big trip in my rig and I loved it. We used to take our mini van which was fine but this is certainly the way to go.
I managed to squeeze 20mpg out of my Yukon going from So Cal to northern Wyoming.
I was happy with the mileage considering the 6.2 is thirsty.

I am lucky if I get 12 after a 1000 miles of highway lol. I just can't keep my foot out the pedal, I hate being behind other people so I am always moving up until there is no one in front of me. I especially hate clusterfucks of car's all grouped together all following the slow poke.

I’m so glad you posted this. I’ve been averaging 10.5-11.8 in my ‘13 ESV and I was starting to think maybe something was wrong….
Reading this confirms there isn’t it’s just my driving. I’ve also been running on E pretty consistently for 8+ months.
around town i get like 9.5-10, I only get 12 after a very long trip, if it gets more than that then the wife was driving it.......
how people get 20 is beyond me, the pickup does better the record is 36 on it but it's more like 11 around town or less
how they get 20 is very impressive. the hybrid don't get much over 25 and that's trying not to he to aggressive.. I think I got 27 at the best cruising along at 70 on flat i10 before tuning the v4 mode off. which is good for a big flying brick but 20 I'm guessing you're just naturally good at hypermiling of something. I'd probably get 15-16 lol.
I guess 93 helps some but my c6 only gets 25 and that's a 6.2 with a decent overdrive, light weight and good aero.

I think that 20 is wishful thinking for the most part. I’ve seen 15 on the highway, but usually it’s 13.
Our stock ‘07 will get 17.5 on country roads at a steady 55. That’s as good as it gets but it’s repeatable.
Put a new conventional battery in the ‘07. Had some points to use so I bought a Duralast Gold from AutoZone. Some of you may recall that I’ve been having trouble with the climate control resetting at night and low battery voltage on the AGM battery has been the culprit. Installed the new battery and the engine turns over noticeably faster. We’ll see how it is in the morning, but the old AGM was only 4 years old.
I was traveling with another vehicle so I stayed around 70 - 75mph.
I topped off with E-85 a couple of times but it was mostly regular 87.
Go anywhere around 80mph and this drops quickly.
I did not manually calculate the MPG and was going by the DIC readings.
