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

[gooffeyguy]

I check it every so often. It's easy enough to do without removing it. The wheels are from an Escalade Platinum. If you're not familiar with them, they don't have any lip at all. The inserts go all the way to the tire bead. My tire guy has to shrink wrap them before mounting tires to protect them. He hates me, lol.

So they're removable? Can't the installer just pop them off, install tire, then pop them back on, or do they not remove easily?

I'm starting early prep for a road trip coming up in a few weeks.

Checked brakes and fluids. While I had the DS front wheel off I repositioned one of the chrome inserts that I jolted when I hit a curb in a parking lot last week. A car stopped in an aisle at night for no apparent reason and like a dumbass I didn't pay attention when I drove around...whump-whump over a center divider curb. Thankfully the wheels weren't damaged other than moving the insert and rub marks from the tire sidewalls which cleaned off.

Cleaned throttle body and MAF. I unhooked the battery and sensors beforehand. No idle speed issues afterwards. It made a huge difference in the smoothness of the idle, especially cold. I should have done it sooner. And holy helmholtz that intake with all its resonator chambers is ridiculous looking.

Also I lowered the spare just to know the process and check to make sure nothing was stuck. I read horror stories about them sticking, and figured I should test it out. Worked fine. Now I shouldn't have a problem if I need to get at the spare on the side of the road, at night, in the rain, because that's when it will happen.

Purty isn’t it. I swapped the tube on thecopcar for a tidier look. I gained 30 hp, and dropped 3 seconds in the 1/4.

Yes I see. Did Gruven ever get back to you? I will also have to instruct anyone who wants to raise the seat height to stand outside.

They offered me some money back to compensate for my troubles. In the end I was happy. The seat still lacks the power to raise my 235 lbs but I need it all the way down and it only would need to go up if my wife drives. She has been instructed to press the memory button, wait for the seat to move and then get in. I think part of it is due to my not getting the large gear on perfectly true.

Last weekend, my neighbor broke a fitting on a small hose while replacing the fuel filter on his '20 F250 (Diesel). He had to buy an entire hose assembly to get that one fitting. It has a few standoffs like that and some miscellaneous clips. He was gonna trash it so he happily gave it to me.

The whole F250??? I still think you came out on the loosing end-Its a FORD!

Wow, that new intake let's you hit 80mph! Lol

 

[Fubar0715]

Maybe wrangler will sponsor him a new pair of jeans...along side Hanes I'd need some new ones after that

After driving away, he changed out of his "brown" pants!

In first gear.

i Went with the whole corsa "cai"...definitely let the engine breathe better, through a lean code until i recalibrated the maf.
Sounds great though! Hoping it'll work with the whipple still.
Just getting rid of the stupid factory intake tube with the resonators makes a nice difference!

hahahaha, 88mph is where its at.

 

[RooTBeeRthe1st]

In first gear.

for my setup, that'd be 11,225rpm.

Each one is held on from the back with two torx screws and a bunch of really strong foam tape. Removing and reinstalling is a chore. They also cost $72 EACH! So I don't want them popping off. In fact, a few are scratched from the PO's curbing. When I refinished the wheels I looked for some. But I've lived with it hoping to grab some for cheap somewhere.

Link to thread where I refinish wheels. Page 2 has a pic of a wheel without inserts.

If these were your wheels, what would you do?

They look awesome.

It won’t work with the Whipple. They’ll supply a tube that attaches to the factory airbox and a high flow filter.

Yeah, I have the tube that Whipple supplied, I'm hoping that that will fit the Corsa air box. Or at least hopefully I can easily modify something to make it all work.

You may have a bad parking brake sensor switch that's not detecting when the brake is engaged.

apply the parking brake, then look down around the assembly there is a switch they used to be a push button but it's probably a contact switch, might be hard to see but it's there. check it to see if it's stuck or if the contacts are dirty, got bent, etc.

I pulled this parking brake switch out and vacuumed up all nice and clean under there. It's a 7mm socket for the bolt. This style switch you can pop out the brass contacts and clean them up. There was some kind of a greasy varnish on them. I used my bench grinder wire wheel on slow speed and light pressure to clean the contacts up. Works like a charm now. Didn't get any after pics, temps are dropping here and I was in a rush. There is a locating pin sticking out of the back of the switch to help clock it into the correct position when reinstalling.

New fancy Sonnax 1-2-3-4 billet piston.

New 1-2-3-4 @ reverse drum all upgraded and assembled with fancy parts.

I spent way too long doing this.
I even deburred some parts that needed it.

Used the old transmission pump to air check it.

This thing is working very well.


Better than it did brand new out of the box...

Now it's time to start looking at wires since everything is super easy to get to.
plan is to flow some fresh solder into some of the grounds.
