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

Well work has been demanding with launching a bunch of new classes at work. Then I'm in the process of building a new house, then selling my current house and getting the ground work established for new business.

I had Discount Tire do all 5 on thecopcar for $250 a few months ago.

5?! I thought the spare tire does not have a sensor on these cars.

I’ve been getting an average of 12mpg e85. I changed my tune to 89/91 BBP tune and on the way to the airport I was getting 18mpg, we’ll have to see what the average turns out to be over time but so far I’m a fan. Lol

I've been seeing 18+ MPG highway if I set the CC to 70mph. Some areas are less hilly than others, and I saw sustained 20mpg for an hour.

Also ordered four hub-centric ring spacers for 78.1mm to 112mm, aluminium.

you will need resistors or bulbs with resistors built in, the only seller I have seen with resistors built into the bulbs that actually worked is auxito
you have to get them from this guy though because others are fakes or not work

On my 1980 it was nice and easy, I just got some flasher units that had a knob on them to adjust the speed of the flash when I swapped all the bulbs out for LEDs.
Unfortunately, these newer vehicles aren't so easy.
I don't like resistors, they seem like a Band-Aid rather than a proper fix. I probably still have some left over from my Subaru that I didn't use though.

Mine did when I needed it. Showed up on the dash a couple pounds lower than all my other ones. Meanwhile the one I took off was completely flat.

How thick are the spacers?

112 - 78.1 = ?

They aren't for making the wheel stick out more, but centering my aftermarket wheels on the hubs perfectly. I didn't realize there was a difference until I took them off the truck to swap on my Nissan winter wheel/tire combo (Nissan also used a 78.1mm hub).

The only other workaround is a BCM flash from BT Dieselworks. You need an Autocal and then he’ll email you the file. His Autosync won’t disable hyper flash for the GMT 900’s. I did the BCM flash on my 08 Silverado.

The AutoSync has programming mode now, so you don't need an Autocal to flash the BCM. The file is either sent on a microSD card that plugs into the AutoSync or it updates over the air, not sure which exactly.

changed out the right side fan motor that was questionable, burnt the connector and one pin was obviously getting hot, motor was about 4-5 years old
