What did you do to your NBS GMT800 Tahoe/Yukon Today?

Oh lol all I noticed was the headlights! Those grill lights are cool.

A noticeable difference in what? HP- I doubt it's much. I'm not sure if I could really tell. MPG- ditto but since my tune I drive a lot faster since it's so much more fun and quicker. But it sure makes it easier to work on the front of the engine, and it looks way better!

Yeah I noticed I got into it a whole hell of a lot knowing its tuned. Since I'm usually all highway driven, I think it runs a lot smoother running between 70-80. Hey if I can more MPG its s gain for me, I baby her better than I would a new 2016!

In your opinion, worth it?

Mine helped a lot with wind steer doing 80+ on the freeway out here. Doesn't do the jerk the truck around nearly as bad as it did when I lifted it.

I don't know why this guy is giving me heartache about it then. Refuses to do it without the fans being in.

I bought my efan OEM harness and fans from an eBay seller. Very responsive seller. As part of the deal, they would program the ecm to turn the fans on. Well, the fans didn't and I hard wired a switch to turn them on when needed. Had a BB tune and the fans now work as they are suppose to. My point is even a good tuner may not know exactly how to do it properly. I have also read that many people get a BB tune before the fans themselves and they work fine once installed with no issue before they are installed.

Installed the 05-06 Electric Fans & Blackbear Performance tuned ECM today. What a difference converting that damn clutch fan!

Efans are hands down the best mod I did on my truck. Funny to think i got a tune just to activate pins for fans which later led to a cammed motor swap..what a snowball lol..

Looking at xl's to replace my totalled one. I really want 04+ so it comes with electric fans.

Speaking of which. Considering a decent looking black '05 Denali XL for ~5.5k$ with 160k miles on oem 20's. Looks like it has an airbag light on... not sure how much I should worry about that.

Any thoughts?

I have a code reader that should be able to pull the codes.

Airbag light is more than likely the front impact sensors. Had to replace one on mine.

I googled it real quickly. That is what I had read. Seems easy enough. How much did you spend? I see $65 @ amazon for a dorman one.

That's about right, I got mine off of Rockauto. One bolt and an electrical connector.
