I got 14.2 after running some Amsoil PI through it. I was getting about 12.5 before that.

18.2 yesterday after 440 miles

If I keep it out of Sport Mode, it does pretty damned good.

I really like that Active Exhaust, though! LOL it only functions in Sport Mode. I need to make a decision

 

[Darkanion]

Does Sport Mode make your foot heavier??

Well, yeah

I just love the way it sounds.

Yeah... I was that way with the Camaro AND the Denali, for that matter. The longer I had 'em, the worse my mileage got. lol

I updated the exhaust on the RAM so "it'd talk a little more." But, I'm starting to think it needs to talk a BIT more than it does now. hahaha

There are so many great sounding mufflers and systems out, now. With these new engines, they just sound amazing.

The price about blows me away, though!

For instance, if you might recall, the GM Touring Cat-Back exhaust for the 2007+ trucks was around $699 on most of the GM aftermarket retail sites.

Now, the Touring kit for a new truck is $1999 on sale, and the regular price hovers around $2199

I was getting 21mpg out of my 6.2 on my trips up to PA to visit mom. I have the GM cold air intake as well as the Corsa exhaust on it. But every since I put the Eibach Pro 2.0 lift on it and got the 285/75-18 Toyo Open Country ATIII tires, I'm only getting 18mpg, which still isn't bad. Oh and this is running in manual mode in L9 to keep the DFM and Auto Stop off.

Gotcha
As you know, my AT4 is already up a bit and does not have the lower air dam, so I am at that mileage point. Mine will only get worse I imagine, as I add mods

I turn my AS off every time i start it, now, but I will start running in L9 and see how that goes

Do you think you picked up anything when you added the bed cover?

I didn't get any different in mpg with the back cover on. I also get less around 16mpg now for the most part because I'm mixing E85. I put 10 gallons of it in to every fill up. My UOA's are better when I use E85. Can't go any higher or I get a CEL. I know it's all in my head, but I feel I get better throttle response and pickup.

Plus it keeps the inside of the combustion cleaner for sure. Not to mention I love the exhaust smell.
