Cool truck and story behind it. But was demarcus trying to shake you down for the brakes or the dealership?

 

Well it has all been through a mediator at the dealership. The salesman who has sold him 5 cars, was the middleman as it were. I do not know if he was trying to make some for himself, I counter offered $1500 and heard nothing back. Either way everything worked out fine still.

Here is the truck when he owned it...

 

The whole truck as murdered out except the windows....
Did he not like tinted windows?

Sweet deal you got there

 

Dallas + Dark Tint = Ticket. They are pretty bad out here. The backs are close to limo. The fronts are 35%. The truck did look cool. Also keep in mind it was a body vinyl, so my paint is all brand new. Not even swirl marks or anything. Oh and another thing, these 6.2's eat gas. I am sure the transmission doesn't help (@ 70 pulling 2000 rpm's).

Thanks man!

 

Mine doesn't run 2k rpm's till 80 something. I get 13mph doing burnouts and 100+ mph blasts. I put a bed cover on mine and noticed a great improvement! Does ur tryck have a CAI?

 

I wish it took until 80. They didn't say anything about differential gears, but I wonder if a transmission would even be built for acceleration that way (2k @ 70). I put it in M and went through all 6 (not at WOT, just cruising) so it does have a 6 sp. I am willing to bet I have gears too.

As far as a CAI (the most basic performance upgrade to most vehicles) it doesnt have one. Though I hear the stock one works really well. What to believe?

 

U have 373's I bet. It's the factory gear unless u have the TE.

For some reason I've noticed my mileage is a tad higher than most 6.2's
It's all in ur driving style...

 

I've got the 6L80 and 3.73s, and show just under 2K @ 70 mph.

fwiw

 

What's a TE?

This confirms it. No gears, but the stock one is performance'ish.

 

3.73 is only factory in NHT trucks, which an AWD Denali wouldn't be. I believe AWD Denalis all have 10-bolt/3.42 combo. However, swapping to 3.73s would be no big deal at all. If you get a minute, photograph the sticker in your glovebox, remove the VIN in MS Paint, and post the rest. We'll figure it all out by reading the codes
