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

I would very much like to get to 400 horse in mine but I also want to do it on 87 or 89 octane. Will see what happens with an afm delete. I’m probably delusional.

When the time comes its gonna be the delete kit, new rings, decked and mild ported heads, port the intake and exhaust manifolds, and tune it. I know that wont get it to 400. But hopefully closer.

It will certainly make more power with those mods. I have dreams of wet sleeves with a larger bore and stroker cranks but the price and performance of a stock L9H crate motor makes such grand designs hard to justify. 403 horses stock! I'm at 307 RWHP now and figure a mild cam, heads and exhaust would bring it to 350, hardly worth the effort compared to the L9H.

Changed out my steering column shroud and shifting leather boot. Boot was old and had holes. Steering column shroud wasn't snapping in correctly

Replaced the A/C belt on our '10. What a PITA!! The parts house belt remover/installer tool will NOT work on a '10 5.3.

I used the lisle li59370, it's magnetic taking the belt off is super easy, putting it back on it's a little tricky due to space but once you figure it out, easy peasy.

you will have t

I also have my spare removed, it wouldn't do me any good anyhow since my tires are slightly bigger than stock. But I can't find the GM repair kit, I tried to buy one from gmpartdirect some time ago, but they cancelled my order saying it was discontinued.

this is the one for the SUV OEM it's $168

The fact that its 100 pounds out of the vehicle doesnt matter as much as its 100 pounds out of what part of the vehicle. Taking 100 pounds off the top of the vehicle is going to make a bigger difference than 100 pounds off the bottom. Weight added or removed from outside of the axles vs in between the axles will also impact how the vehicle feels.

He should swap out for a XFE mod. as well as do a full hybrid body parts swap Hybrid rims, front /rear bumper,, aluminium hood & tail gate that will take out another 150 pounds..

roof rack delete

that will improve it a lot and get him 2-3mpg more from the aero dynamics

3.08:1 final-drive ratio

Bought some of these to try out because I have had somewhat good luck with there carpet cleaner before, these seem to work pretty fair in general but when trying on the headliner it did leave some of the blue thread material behind, a follow-up with a regular baby wipe removed it

With 4 kids, I need to get a couple tubs of those to keep in my vehicles.

I replaced the rear bumper step pad on the Silverado and fixed a couple things.

The aluminum hood sounds interesting. Lift gate too but I don’t know about that. I’d really like to buy the tooling to do carbon fiber work though. Full carbon hood and lift gate skin, fenders, and roof. Delete the sunroof.
