Looking for some input from Duramax owners, what is the most effective way to get more power and improve fuel economy on this engine? I have heard that changing out the air intake and installing a larger diameter exhaust makes a nice improvement, is this true? If this is the case what brands work best and are still safe for the engine? Thanks.

If you want fuel econ then go with the edge chip in my opinion. If you are get 18 now you can get up to 24mpg in econ mode and a soft foot. I have problems with the soft foot myself...
Don't know about the exhaust, but I know it was much money for me. I'd rather put it into a sled.

dual 6 inch stacks
This is one of the best intakes for Duramax, friends truck. He says the truck runs a lot better since he installed this and also his mileage improved. I helped him install this and the Injen is very high quality system. The shinny tube is solid aluminum. It an expensive system but IMO worth it.

dragon,
He got it thru AMSOIL. They use a special AMSOIL (dry) nano-fiber air filter.
I come up with model PF7075P List $676.00 Preferrer Customer Price $488 for your truck. But, look it up to be sure I got the right year using this link ---->Appliction Guide When you find your year, make, model product info screen; scroll down on the right side until you get to filters etc.
If you are not a Preferred Customer (Jared is) you will only see list prices until you add the Preferred Customer option to your cart and then you will see the wholesale price.
Jared claims he can easily tell its increased his performance and he been boasting better mileage also. He does drive a lot of miles, over 100,000+ on his 2007 classic CC
It took about 1 hr to remove the old box and install it. He did most of the work, I handed him tools. LOL

Yah, the price is up there but so is the quality. No cheap plastic parts in these.
I had one on my 2008 GMC and I got one coming for my 2010 GMC 5.3L.
Btw - The filter box part (black tube and SS box) comes assembled as you see it on the truck, not in individual pieces that have to be put together.

Check out Quadzilla. It's a flasher. The downloaders you're actually downloading all the programs and then can switch on the fly, because you're just selecting between the programs. The flasher you pick which setting you want and download it. I had the Bully Dog in my truck for awhile. It only had three settings and you had to be on the top one for any power. I like the screen and such, but the power was nowhere near the Quadzilla. I went back to that. Once you have the flash you like you really don't change much. With the Allison smart trans every time you change you should start from a stop let it go thru the gears at 25% throttle then let it decelerate by itself, then 50% same way, then 75%, then 100% It lets the trans learn and adjust to the added power. I only run mine with their 70hp and I forget the torque increase. That is where Quadzilla really has it dialed in. I know several people with the edge that have had problems. My close buddy bought it and was really disappointed when he started playing with it. I ate him alive with whatever he threw into his with the 70hp I had in mine. He returned that and got think it was a something, forget, but still spanked him. He got worse mileage then me also and he was on the expressway at 60mph. I could never do that! I get between 19-20 around town and 22mpg on the highway with the air on and doing about 85mph. I had a K & N in the stock air box. You could hear it a little more and feel it off the line a little. I got an air raid on it now. Maybe a touch more then the K & N The bid difference is on the highway in the summer I saw the air intake temps drop from about 25 degrees above the outside air temp to within 2-3 degrees. Good luck Charlie
