Just curious if your mileage is calculated manually by you when you fill the truck or if you are reading off of the DIC. I have found that the DIC mileage is way off. I have an 2004.5 LLY motor in my GMC Sierra Crew Cab Short box. My lifetime mpg average at 15,000, calculated by me from fuel reciepts is 17.8, this was a mixture of highway and city. I just finished putting a predator programmer (fuel economy mode selected), MAC intake, and a Jardine 4" exhaust. Today I took the family to Chicago and back running 75mph the whole time and average 20.1mpg based off of actual miles traveled divided by the actual fill...the DIC showed 26.5mpg??? I am very pleased with 20mpg. I believe I can get up to 21mpg if I hold it at 65mph, or essentially keep the motor below 2000rpm which is where everyone on the forums states they get the best mileage. Glad to hear you have the Allison with the 6 speed.
Cheers,
Brian

Larger Tire Size Calibrations

Sorry fellas, I mentioned before that I took my 05 CC D-Max to my dealer to recalibrate the speedometer for the 285.75.16's, and now I am beginning to wonder if they did anything at all. I recently installed the Edge Juice with Attitude, calibrated it for the 285.75's and there is a noticable difference in the speed. I am now thinking that I am actually getting better MPG than shown or hand calculated, because the truck is actually going further with each revolution than the computer is calibrated for. I guess the only way to find out for sure is to get on the open highway, reset the tripometer and take a look upon passing 100 mile markers. I'll bet the computer says I have traveled less than 100. (sure hope those DOT boys are accurate!!)

I am considering buying a new 2006 DMAX, 2500HD 4x4. What kind of everyday mileage are you getting city/hwy and is your DMAX a 4x4? I plan to use the DMAX to pull a camper but the majority of the time will just be for driving back and forth from work. Thanks.

Is it the new 360 HP / 650 lb-ft DMAX? I am also thinking about getting a 2006 2005HD 4x4 with DMAX. I was just building one on chevrolet.com and saw a 360 HP DMAX as an option for 2006. I ruined a pair of perfectly good pants!  Dang! I guess the Torque wars are far from over. Dodge and Ford better step up to the Chevy, or Chevy will just keep eating them for breakfast.

update....yes there is. If you are looking at adding the Edge with Attitude monitor to your 2500HD, and it has a sunroof, the overhead console mount on Ebay will not work for your truck. Also the black plastic one that says it fits all makes and emodels will NOT work if you have the sunroof option. You have 3 mounting options: Use the supplies mount, use a pillar mount, or what I did, drill a small hole in the smaller of the two lower consoles for the wire to go though, and sqeeze in. Its rare that people in the truck ever even ask, "hey what's that?" It just doesn't look like it has been added aftermarket. If you DONT have a sunroof, the overhead console mount with the two built in auxillary switches looks awesome.

the dealer finally figured out the problem. it was a clogged fuel filter!!! i have 16,000 mi and i can't believe it was clogged!!! and they wanted to charge me $180.00 to fix it. say's it wasn't under warrenty!!! say it's like an oil change. good thing i spent $49,000 on a chevy. might want to get your own from a parts store!!!!!!!!!!!!!

at a place in Tallahassee, FL called MINCO
If your nowhere near here, look on EBay, I've seen them there for, I think around $40-$60. After you change them out, you'll need to get your truck re-aligned. If you want to get that "cadilac" ride back after the torsion key install, switch your front shocks out to the Bilstien 5100 series. These shocks are longer to accomodate the 2.5 inch increase in height. I didn't do it at first, and the ride was pretty bad going over even a speed bump at low speeds. It seemed as though the truck would "top out" causing the truck to slam up and down. If you do it (highly recommended) go ahead and spend the extra $100.00 on the shocks. I have seen the shocks in accessory catelogs for less, but I had minco order and install these as well. I get lots of compliments at stop lights, gas stations, etc. for the way the truck sits level. Good Luck.
