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

[Doubeleive]

After 55 years of wanting and waiting for a forced injection vehicle, I finally bit the bullet and installed a Whipple 2.3L supercharger on my 2007 Yukon XL Denali. I'm looking forward to some fun times in the near future.

I see that you're going to start the New Year right!

 

[RooTBeeRthe1st]

well I requested some changes this past summer and they sent me 2-3 different tunes and I mistakenly thought I had put the original back on it but after digging around I found it was really from july/24, how I screwed that up I don't know and how I didn't find the 2021 one on my computer until several tries I also don't know I searched 4 hard drives because I normally backup everything and still only have 1 copy so going to back it up now......

At least you got it sorted!
I actually need to find my backup though the OEM tune now that I think about it

Been busy with work and end of year. I picked up this 2008 LTZ two weeks ago with 115k miles. It's all stock with the exception of a Kenwood HU and new speakers all around.

Keeping her stock. Will be replacing the work out shocks with new OEM pieces soon.it has the Z55 suspension on it.

That thing is clean.
Someone took care of and loved that Tahoe.
Congrats.

I just saw one listed here last night locally w/56k on it $15,000 probably will be gone quick, has a couple little issue's but no deal breaker i can see, the dash is probably cracked so they avoided picturing it typical.......

thats a nice find too! About once or twice a year I tell my wife I shoulda bought a Suburban.

Swapped the heater hose tee's out today. Between several threads here and watching videos of various skill and quality levels, I got the originals off, connections cleaned and new ones on in less then 30 minutes. Pretty pleased with that. Hopefully this is my last thing leaking.

Tuesday is emissions testing ( which is stupid ) and plate renewal. Also since my pass side rear door speaker comes and goes depending on how hard my kid slams the door. New infinity speakers will be here next week.

Seems like a good deal on a well kept truck.
Same here, there are times I wished I had the longer Suburban or XL, but then I drive through parking lots and am glad I don't have the extra length to deal with.
Seems the striping in these parking lots is made for parking a Prius.

Been driving Xl's and long bed pickups for 30+ years, no problems parking. Parking garages can be a little tight but you just take your time and it can be done, won't trust a Valet to do it though I'll park on the street instead

I dunno. Paint on the driver's side doors looks off to me and the moldings are coming loose. The dash is for sure cracked above the dr side center vent. No pic of the DR seat where the rip usually is. The far right dash vent looks broke. The trailer hitch area looks repainted.
The Door paint might just be the camera? A guy needs to really go look at it and go over it real good. Might turn out to be a good buy.

I have a CDL so it's not like I haven't driven large vehicles, it's just that a lot of parking lots are so small it's a pain to maneuver around in them.
Not only that, most people that do drive these larger vehicles don't know how to actually drive them and they make things worse.

I have driven or operated dam near everything I have been a transfer driver, shuttle driver and a valet..... among other things and I am sure most valet are very capable drivers but I just don't trust them lol
my personal issue with considering or being a commercial driver is I just have a heavy foot
I am also very impressed when I see a guy driving a 53 footer flip a u turn from the turn lane into a 2 lane
not like the "swift" drivers I have seen literally drive into each other in a yard where there is 500 ft of open space on either side of them lol

Didn't "do" anything per say but thanks to the fine folks on here I have gone ahead and ordered a new front crankshaft seal [296-02 GM OEM seal] and ARP harmonic balance bolt [234-2503 - link below too]. Noticed some dropping on the floor coming from the oil cooler + oil filter areas which annoyed me (new cooler lines I installed are <5k miles old), but when looking forward I noticed it stemming from the front and sure enough, the little sensor by the harmonic balance is all damp. I am assuming here that it's in fact, the front crankshaft seal and not the entire front cover... guess I'll see once I get in there though.

*Any recommendations on LS-based motor harmonic balance removal and install tools??

I also bought some new ARP 12-point exhaust manifold bolts [134-1202 - link below] for someday in the future when I'm feeling frisky and lucky to attempt removal of what's on there now

Realized the other day that chunks of foam are coming with me every time I get out of the car and I can see and feel metal springs now. I guess 200,000 miles was too much for the driver's seat. Bought a very expensive(relatively speaking) GM replacement foam and seat cover from some eBay seller in Phoenix who only has one of each in stock.

This is the tool to remove LS crank pulls/harmonic balancers, after you blast the bolt out.

AutoZone also rents it, but they call it a Chrysler pulley tool. Same thing.

EDIT: For install, I used a 1/2" torque wrench that went up to 250 lb/ft. on an ARP bolt set to 235lb/ft. in one hand, and jammed a long breaker bar through the spokes of the balancer in the balancer in the other hand, and just push/pulled until it went "click" 2x.

Replaced headlight bulbs to help melt the ice/snow over the winter. LEDs are great, but don't produce heat.

Also, replaced both rear O2 sensors with some GM (NTK manf.), and swapped in a new transmission mount while I was under there... preventative maintenance.

I picked up some new oil g a filter, but will wait until I hit 5k miles to change it.

Not sure about Tahoe, but Yukon lights are quick/easy to pop out, contrary to whatever crack the shop was smoking the last time they quoted me an hour's labor to do, for one side. It took 5 minutes to do both front bulbs.

Labeled the LEDs to put back in after spring. Each bulb is clocked to "aim" the beam pattern.

Factory fart-snirfets, and the AT mount. All three came out with zero drama.

Buddy sent me some goodies from NC, so of course I payed myself with one.

did you break the clip off? you should have to reach inside the splash guard with a 10mm and loosen the bolt up to get them out (each side)
