What did you do to your 2015-2020 K2XX Tahoe/Yukon Today?

Thats a good idea also,,,, like you said, flat spots were the main issue obviously. its 18 months old and only has 1800 miles on it. everytime we do drive it, it thumps down the road for a while until the tires warm up. I need to get a set of those for the Corvette.

I know its not going anywhere till March or later so no point pushing it.

plus, these are the 2piece set, total 10” rise. Good for 6k lbs. I usually use one set of 5” for one car, another set of 5” for the other. Both have the grooves for the tires.

Your lucky you don't drive a Ford or Toyota the GM is a piece of cake compared to them.

Installed a Range device. Nothing pissed me off more than my Tahoe lumbering in V4 mode. None of that crap anymore

How’s it working ? The sensor is the last thing I need to install in my 19’ burb before I send in my files for the BB tune.

I like how the truck moves with E60-E85 (60 to 85% alcohol). Almost no knock retard that I can register, about 400 hp at the crank. You feel like you have a 6.2 under the hood - e.g. lees downshifts, and almost immediate throttle response. The truck also feels sluggish when running on 91 pump gas or lesser ethanol mixes. Haven't had an issue yet with cold start ups, but it will get more frigid here in South Dakota.

Changed the oil/oil filter today, along with the rear differential fluid. I Was going to change the transmission fluid as well but still Waiting for the gasket and filter. All Amsoil of course, as it should be.
