I have owned both. 2010 Tahoe LTZ and a 2010 Denali XL. Those have totally different suspension. The LTZ has magnetic where the Denali has air. They rode completely different. The Wife and I like the air ride better for the smoothness. The Tahoe ride was very harsh. The Denali sat lower with...
I recently had to replace the vram because of a stuck silonoid in it. I am pretty sure it was from bad oil. I am the third owner of my Denali. The first owner dealer maintained it up until 60k and I'm not sure what the second owner did, but when I pulled the valve covers the where stained brown...
With the 6 speed transmission 3.42 are the same as 4.10. So going with that high of a gear is not beneficial unless you are going to be doing a lot of off roading.

So today my wife got into our 2010 denali and when she started it the only thing the dash that was working was the battery guage.
She turned it off and started it back up and it works again. But because of the way that I am I want to fix it before it becomes a bigger problem.
Has anyone...
I ran a DDM 35w hi and low kit on my 2010 Tahoe with out any problems. But what he is says is that there is always a chance that the stock harness can not handle the flow of current being pulled and heat up possibly catching fire.

I also say Denali. I owned a 2010 Tahoe LTZ fully loaded for a year then traded it for a 2010 Denali XL. I will take the 6.2 in a base model over anything. I get better mpg with the 6.2 then I ever did with the 5.3

I would hate to see you throw parts at it but everything I am reading says that it could possibly be a fuel pump if you are having a hard start issue as well.

With BB if you buy the auto cal you get tunes for the life of that vehicle. So if you change something just data log and email them and you get a new tune.
I paid 600 for my auto cal and tune. If you pm @JennaBear she will be able to answer your questions.

I will take blackbear over the off the shelf programers because I know that tune was made for my truck and not some generic wanna be tune.
