What have you guys seen in your mpg after turning off the DOD. Did you do anything besides deactivate it? Tune?

Trying to figure out if it's really worth turning it off or if everyone is just paranoid and turning it off. I'm not as worried about having to pop the heads off as most, I'm a tech with tools and a shop readily available, and LS and LT motors are really easy to pull heads on so not that big of a deal to me.

I will say, so far i'm not a fan of how it feels in 4 cyl mode, I've only had the truck 3 weeks and still adjusting to it but now that I can actually feel it switch over and back from 4 cyl it kinda sucks. I didn't notice it the first couple weeks.

I didn't see any change after turning it off

I lost maybe 1mpg on the overall with most of it on the freeway stuff. Getting 20-21 highway in my 2012 is still just as easy without it enabled.

My city gas mileage is always garbage.

with afm I would fluctuate between 25-30mpg on the freeway. With it off I hold a steady 25-26. Afm is a joke. The truck feels better with it off. And between fillups it's hardly a noticeble difference

I do have a 16 regular cab 5.3

The second day I had my truck I did a 12 mile trip down the highway grannying the **** out of it and got 33.1 mpg over that 12 miles of highway only, the next day I drove back to the same place but drove normal and used a lot of side streets and normal driving and my average dropped to like 17. In other words I fully agree about the city driving

I hate the way it feels and the hesitation going in and out of 4cyl.



Again thanks for the info guys I've gotten a lot of help here in a short period of time.

my 6.2 014 mileage stayed the same with dod off and tune made the truck come alive,my 6.2 016 mileage tuned dod off,picked up 2 mpg and ran like a scalded cat.

I wanted a 6.2 truck so bad but I looked for months and it was going to cost me at least 10k more to buy a similar mileage denali truck than my full option slt so i'm stuck with the 5.3 but have most of the denali options, But $200 cheaper a month for 60 months makes me happy enough with the 5.3.

I hope to find a 6.2 someday that I can afford and slap in it in this truck.

Appreciate the info, congrats on the 6.2 truck.

My daily routine maybe sees a 1-2mpg drop. I average 16-17 and used to get about 18 average. Highway trips I lost maybe 3mpg, going from like 24 to about 21.

I didn't buy a full size v8 truck for the economy.

I have a feeling there is no difference because others are seeing gains from the tune itself as well.

Has anyone tuned their truck and then done the comparison, or are you all just comparing stock to tuned?
