I purchased a Yukon XL Denali SS. This has all the bells and whistles on it, it has one Alpine IVA D310 a 7" retractable screen where the 6 disc changer was on the middle console of the dash, and it also has an Alpine plain Retractable 7"Screen where the Navigation was and a 19 inch drop down screen in the back mounted around the moon roof. It has the Ipod adapter that can run your Ipod from the Alpine head unit and also a IVA M300 Navigation also connected to the Alpine head unit. So I can watch a movie on all three screens at once or I can watch the movie on the 19" and the upper &" and the bottom Alpine can be used for the navigation all at once and it tells the directions while the movies are still going. Plus if you got all three screens goin on a movie the Navigation will automatically jump in when we need to make a turn. Now to the outside. It has 23" Giovanni wrapped with Kuhmo STX directional tires. It also has 2" spacers to have the wheels stick out of the wheel well about an inch. It has a Billet Grille on the Top and bottom. They removed the towing hooks and installed the towing hook. I got LED tail lights, plus smoked out front head lights with Audi LED running around the bottom of the lights when the running lights are on. The Head lights are halo lights, plus te lower lights are are black and have LED lights with 10 LED'* on each bulb. K&N Cold Air intake and Pulse plugs instead of Spark Plugs, they have small capicitors on them and they are suppose to increase HP and MPG. It has Three SS emblems on each side and one on the back. PLuse two on the dash and 4 emblems for each door. Plus the windows are tinted over the factory tint all the way around so you can see anything inside the Vehicle. It also has a Viper 2 way auto start with alarm. Plus start app on the Iphone. it lets you know if a alarm has been triggered and you can start it from anywhere in the US. Is this an SS or just a decked out Denali??

SS is a chevy thing not gmc

That is what I thought but he had SS emblems on both sides of the Denali, the rear end next to the Yukon XL and it had an ss on the driver side where the airbag is and an SS emblem on all four doors. The seat head rests were even embroidered with an SS?? Could I have a case of false advertisement??

What year?

It could have been done by a conversion company just to sell a truck at a higher price.

So, what about the twin turbo intercoolant system that puts out 612HP on the dyno?

Wow, this baby must really haul..got some pics of this beast?

Yeah, I'd love to see pics too.

Especially of the engine.

Its a 2004

it only has one turbo, I didnt know the difference between one and two it had a stainless steel pipe running into the intake and it was said it was a twin Turbo so I got hit again with false advertisement, sorry to all who thought is was a twin.

Ok, what about the pics Mouse requested? I myself would like to see pics of the engine bay.
