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

[CMoore711]

picked it up yesterday, dealer nailed em for $3020.61, more than I thought it was going to be

Better then getting nailed than you.

Filled up with about half tank of E85 for first time. I had something called regular 88?? In VA once. Only 2 stations near me in NJ have E85, 1 is at the airport and they charge basically premium prices. Power Gas in East Orange has it for 3.05 today. I’ll see if she likes it through the week.

A bunch of stations in PA carry it, if you're ever out that way. Something about the higher elevation, I think.

I go to Philly sometimes but while technically Pennsylvania it’s a big difference from PA. Any stations close to the casino out there?

It'll like the E85 for sure. Fuel economy dips a bit, but it'll run smoother.
I put a full tank of E85 through my Tahoe every few months. Seems to kind of clean things up a bit.

Butters and Sheetz usually have a few pumps with e85, but not always available at every pump.

 

[CMoore711]

They just put a Sheetz and Casey's about 4 miles from my house and they each have about 4 pumps with E85. It's been working out really well.

Gas Buddy will show where E85 is available. I don't know about the phone app, but the online (PC) site can filter by county, etc. and map the locations.

Tire rotation, trans drain and refill with new filter, old fluid looked red with light brown tint @20k miles since rebuild and also did the front brakes…. Now I just found out I have a P0711 code and need a new TECHM so that’s the next project in early October. I’ll
Post about that for the 6L80 guys in here.

PS— I didn’t need to remove the exhaust to get the pan off the trans….

Good stuff!
Also impressed you were able to get the pan off without removing the exhaust.

Went to smog it this morning after unplugging the range AFM disabler last night. Apparently didn’t drive enough miles for it to be “ready” to be smogged. I’ll try again tomorrow after driving 50+ miles today.
All this smog crap is such a joke.

Can’t wait until I mechanically delete the AFM and have it properly tuned.

I did that on mine a while back. I was actually pulling up to the inspection station and noticed it. Unplugged and went on in since I was there. Passed okay. Which confirmed my guess that unless you’re in one of the few counties here that does an emissions test, they don’t plug in the computer.

Yeah here in Scottsdale they plug into the obd. Which is annoying.
They plugged in and rejected me and gave me a print out that stated "evap system not ready" and "o2 sensor not ready"

I swapped in a Denali cluster a few weeks ago, and the only downside is that I lost oil pressure and transmission temp. I know I can get it through Tow Mode, but I want to be able to see it whenever. After a bit of research, I was able get Torque Pro working with Android Auto! Woohoo!

Changed the oil last night and discovered that one of my new sway bar bushings has torn and squeezed itself out. I wouldn't even say the front end was all that floaty before but today I towed the drift car with it like that and MAN it felt like I was towing with a lifted jeep with the sway bar unhooked. I highly recommend skipping this experience if you can.

Black bear's tune really did make the powertrain dramatically better for towing but it's just so damn slow compared to my Duramax that I find it harder to appreciate.

what the axle ratio in the duramax? the denali should have 3.42

 

[Doubeleive]

not sure how long this has been on the market, have not heard of it until now, but for those with the 8 speed here is a B&M dipstick option

3.73 but I've got 35s on it at stock height and a bigger turbo so the Duramax is at a gearing disadvantage for sure from stock. The Denali feels great around town and is definitely quicker unloaded but it's just not even close on the highway let alone while towing. I have been intending to put 4.10s in the Duramax for years to help overcome the tire upsizing but I've just always found other things to spend that money on.

replaced a/c condenser

so many bolts & parts to remove... SMH @ GM engineers, lol

Hooked up the camper for a maiden try out before we head out camping/hunting this weekend. The Sub never had a hitch put in the receiver before.
All lights from the Sub work at the trailer. And the Sub seems to be connecting the Sub primary battery to the trailer.
The trans DEFINATELY seems to be running about 10-15 Deg hotter than the 2011 when towing. My guess is that the stock temp valve isn't fully open until 200DegF? Anyway I have the 158DegC valve on order. Can't run bypass because I need to keep stockish to keep my warranty.
I know it didn't happen if there is no picture - I forgot to take one hooked up. This will have to do - after I unhooked and poured a cold one.
