Article comments for Full Test: 2007 GMC Sierra Denali - The 2007 GMC Sierra Denali is GM's top-of-the-line luxury pickup, but it emphasizes the truck part of the equation as much as the luxury part. (more)

I put down 350 rear wheel HP with just a intake and tune, I never dyno'ed since adding an exhaust. people at the track could not belive I was running that fast with minor mods. Folks were looking under the hood for NOS....LOL! |

Replying to: 1oldcarguy (Sep 16, 2007 7:56 am) What I like about the truck is the feel. It is fun to drive, I look forward to it. I enjoy the music and it's sure-footed stance with those enormous 20" tires. I like the way the back seat folds up to carry stuff home. The gas mileage has been pretty good as far as tank fill ups. I have not measured it but know it is far better than the guzzler I used to have. As far as power, no it does not feel as strong as it should but I suspect it is in the gearing. If you punch it at about 55 it will scoot. Feels like the thrust of a Corvette I had when I was young. No low end power but that sucker would fly out on the road and this Denali does, too. Would I recommend this truck, YES! I even recommeded to my General Manager and he bought one, too. He likes his almost as much as I like mine. He was upset about the spare tire thing, but I told him that is what AAA is for! Knowing what I know now, would I purchase this truck...YES! Everyone has opinions and I say GMC did an excellant job with this truck. Are there things that could be improved, probably. But what in this life isn't that way...nothing! There you have it from another Old Car Guy!

Can the nav screen brightness be adjusted? There is an automatic mode that at night is to bright. I know there are manual day and night modes you can adjust the brightness and contrast settings. So in order for me not to have the bright screen at night I use the manual modes. Wish that the manual settings could become the default settings for the automatic mode. I have to adjust that screen at least twice a day. Any ideas? Thanks Troy

Well, my boss just broke a 30+ year tradition and bought 2 new non GM trucks for our company. I usually drive the Denali, but last week he took it for a few days and got frustrated trying to find something in the glove box at night. (no light inside anymore). He has trouble with 'night vision' and glare. He does not like being 'lied to', saying that he didn't like the fact that the marketing people mention perimeter lighting, yet the perimeter lamps under the sideview mirrors are not there anymore. The overhead (reading lamps) are not recessed (he says they have a lot of glare) and cannot be aimed, so he got frustrated at those things too. This is really a sad situation. His bottom line to me was: "If I buy a upper end truck, I expect a few useful amenities for my money. I don't like buying a product that I feel the manufacturer 'chintzed' on the design." So thanks GM. Now all I have to look forward to driving in a few years is a non GM product. You may have saved a few bucks on the design, but you lost a loyal customer.

Replying to: markisliev (Oct 21, 2007 4:06 pm) I am very impressed with how fast the truck is, but I want it to go faster. I am considering putting on a K&N 63 Series Aircharger Performance Intake Kit part# 63-3058 that has an Estimated Horsepower Gain of 17.54 HP  4917 RPM. I am also considering a Superchips Cortex Programmer (I think these came on the market in September 2007). I spoke with a rep from Superchips who told me on the 6.2L 403hp engine, the performance program would add 32hp & 35 ft lbs torque. These two additions should put the truck at 452 ½ horsepower, right? If anyone has had any experience with either of these products on the 6.2L 403hp engine, please share your opinions. I want to make sure I will be able to feel the difference before I spend $750. Thanks.

Replying to: 2007denali (Nov 30, 2007 1:52 pm) The K&N intake is ok....I prefer the outlaw intake or maybe even volant, it's doesn't suck in warm engine compartment air... BTW my latest time is 13.87 99.91mph...I even trapped above 100mph on some runs... Here is a video.... Denali 13.87

I've been very happy with my 04 Z71. Love the Full time 4x4, my only bitch about my truck is the fact chevy can't find a freakin cluster to work right in my dash..any way Thinking of trading my ride in for a new AWD Denali. Question 1. I'm getting between 16-18 hwy at 70 mph with a engine programmer, what does the Denali AWD get? Question 2. I push my truck to the limit off road at work I would end up lifting the Denali just as high as my Z71. 6'' for room for 33" tires, it would get tore up at work as low as it sits stock sooo how is the AWD system? Any one had there Denali in any mud or deep snow? P.S. I don't need any comment about why would I buy a Denali and use it off road I just want to hear if any one that has one thinks its capable as much as a 4x4 is.
