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

[swathdiver]

Take any pics of the spots?

No, I always forget and never have my phone with camera handy. Will take some on Wednesday as we finish it up.

I was supposed to be in Tampa today, a relative had surgery at the Moffitt Cancer Center. I'll keep ya posted on when plans get finalized to head up your way.

Best wishes and prayers to your relative sir.

I'm trying to not get my hopes up a whole lot since there are some extenuating circumstances beyond our controls, but the deal's looking very possible. I really doubt I'll have dyno figures, but I live less than 5 miles from a 1/4 mile strip so I can calculate from that.

Now I'm wishing I had gotten some baseline runs at the track.






...Hmmm. I'm 8 miles shy of 200K. It'd be cool to hit 200K miles at WOT on the big end of the strip!

I really wanna hit the drag strip. Im not too far from woodburn but i can never figure out what events i’m allowed to show up to based on their event schedule. I really wish they had something like yellowbelly where its $20 to get in for the night and you just make passes

went and picked up the running board and splash guard, learned how to break the chrome trim piece off the board I bought had some chips in the chrome on the front part, I managed to salvage my front part, then I was comparing the back part and thought mine looked better so I proceeded to break both so now I have to order a new rear piece, I was hoping to find some aftermarket ones because each piece is a $100 and each side takes 2 pieces but no luck so far, but I learned something new you have to take the front end cap off to remove the clip to get the front chrome piece off from the front, then the rear chrome piece comes off from the back first. splash guard went on easy peasy.

Sometimes our lessons are expensive. Knowledge ain’t cheap.

Such nights are usually called "Test-N-Tune" and happen on weeknights.

March 8th, 15th, 22nd and 28th for you at Woodburn!

Ain’t that the truth!

Actual tech 2. Finally decided to pull the trigger when i get back to the states. I thought you needed a computer for programming and certain features.

I’m late in the game to respond but you’ll need Win10 to use the ACdelco TDS if you want support; their tech support is good. Buy a genuine Tripp Lite Keyspan brand USB to Serial converter ($28) too don’t use a Chinese junk substitute.

Damn I wanna go. $50 is pretty good. I need to do more data logging and get a helmet before I get serious about going though. With my tune file theres two things I need to do. 1 is make sure I’m not getting any torque management limiting throttle, though that’s different than turning it off. You don’t want it off on a mostly stock 4L60e. Good way to get 5 neutrals. Second is I need to dial in the rpms for the 4 -> 2 at WOT. Right now if I’m doing 70 and smash the throttle it won’t downshift to second even though there’s more than enough rpm for it to do that. It’ll only go to down to 3rd and its not making high power there like it would in 2nd. Not needed for drag racing but its something to look at.

My neighbor also has a full set of 17” steelies for the tahoe. They have a new set of winter tires on them from 7 years ago. I think I’ll take two of them to the drag strip for the rears because they’re gonna be way lighter than the 20s and I won’t feel bad about doing burnouts on a $1500 set of all terrains

That's how State Capitol Raceway by me is. Unless it changed, it's $10 per spectator and $20 to race.

Yup! At my track, unless a formal event takes its place, Fridays are usually TNTs. Sundays, too, but they're more of daytime events and we prefer to go in the evening/night.

Before life took over, I would grab a daiquiri from a drive-thru place down the road and spend a few hours there almost every Friday night.

You shouldn't need a helmet for test-n-tune with your truck unless you expect it to run in the 13s. I don't bother with burnouts, the launch area is plenty sticky for the KO2s, which I think actually slow me down, like driving across fly paper.

I think the race fee is less than that too on those days/nights. But once you get a soda and something to eat from the geedunk...

Oh good to know! I think I should call and ask. I probably won’t be able to get there this month but next month hopefully.

Also lmao. 13s would be hilarious if it did it. I’ll take the back seats out and see what happens

Oil cooler lines on the 6.0. Turns out you have to pull the driver side motor mount to get them in/out. Good thing I had already replaced them a few months back so the bolts came out easy.

 

[swathdiver]

Well, I messed up the paint correction on the bumper. Went out and put a third coat and forgot to shake the can. Came out flat and splattered a little. Shook the can for a few minutes and tried again. This morning is still looked terrible so I sanded it all off and will start over tomorrow.

Finally got a sample of fluid out of the transmission, from the top line that goes into the radiator. That'll go out to Blackstone Labs with the ACDelco engine oil sample soon.

Where we’re going, we don’t need roads!

Tow hooks are in and replaced one of my HID ballasts. The formerly empty tow hook spots were bugging me for years... not sure why I waited so long. Nice that they have purpose now. I’ll be retrofitting some stock headlight housings soon. The passenger side u-bar started to go out. Then just need to install the blower and some big Wilwoods and we should be ready to party.

Your truck looks good.

I keep going back between lifting or lowering mine

Thanks, I might bag it at some point way down the road

If those are Anzo’s you can retrofit them with the brackets made for stock Denali headlights, I believe. I did my Denali Anzo u-bars with them.
