Re: 6.6 Chevy gas engine
ksss wrote: My brother just picked up his GMC Denali 3500 SRW, CC/SB with the 6.6 gas. Traveling across parts of Eastern North Dakota, we got 14-15 mpg on flat roads empty. This truck would need quite a tail wind to hit 20 mpg. Very nice pickup though. Note that the claimed 20mpg was with the cruise set below 60mph.654Views0likes0CommentsRe: What is your speed uphill?
I run my 2001 up to just under 1200 on the EGT gauge and just hold it there. Last pass I was at about 40mph or so, I just got in behind another truck and went to the top and admired the new diesels as they went on by. These new trucks are just amazing!520Views0likes0CommentsRe: Big Tires pulling Small tires.

No, you can’t. That would be nothing more than a variation of the trick question: “Which weighs more, a pound of feathers, or a pound of lead?” The tires spin at a higher RPM, but the MPH is the exact same as the truck pulling it. :S :):) A track loader is moving 8 MPH. How fast is the pad on the ground moving? The bottom of the track isn’t moving at all relative to the ground, same with the tire on a truck, the bottom of the tire on a truck isn’t moving for the moment in time it is touching the ground. If a truck is moving 70mph, the bottom of the tire is moving 0mph, and the top of the tire is moving 140mph.565Views0likes0CommentsRe: tuner chip
So according to that article, if you change your gears, you can’t change your computer to compensate. I’d check with someone there about changing gears and reprogramming your computer to make sure those modifications are ok. I looked at the website for the chip you mentioned, it doesn’t give me a good feeling and I wouldn’t trust it. Going from 3.73 to 4.30 will gain you about 15% torque, I think that is by far your best bet.283Views0likes0Comments
