Alright guys I was wondering what tune you guys are running for better gas mileage. Looking to pick up a few mpgs if possible. I have a 2011 crew cab going to be installing 3" leveling kit and 33s. Is there any way to save a couple mpgs?

 

Honestly if you're adding a lift and especially 33's then there's little you can do to save MPG. You could re-gear the truck to accommodate the bigger tires, run a tune, upgrade the exhaust, get a better filter (I don't completely agree this gives a better mpg worth a damn but I've seen people suggest this anyway). And of course, don't be a lead foot. I've gotten about 12.5 mpg city in my truck.

 

I'll be surprised if a tune increases your mileage and you're def. going to take a hit with the larger (heavier) tires.

It's been my experience that keeping your foot out of it is about the only way you can keep the mpg's up. That and keeping the truck well maintained.

If you do get the tune I'll be interested to hear if it did help your mpg's. It didn't help mine.

 

Trucks already got 3.73 gears really don't need to do 4.10s i do have a cat back exhaust and planed on doing a cold air intake. I didn't​ think think there was much I could do to save mpgs but I thought I'd ask

 

I was debating on tuning it or not, I was going to see if there were mpg gains I could get out of it first

 

Best way to save MPG on a pickup with a 3" lift and 33s is to buy a Focus.

As others have already stated, with heavier tires and more of the un-aerodynamic suspension/drivetrain exposed you're going to lose MPG.
I can just about guarantee that any tune you get will cost you more $$ than any fuel savings you MAY get. And are unlikely to get.

Best bet is to enjoy what you've done, and don't drive it like you're fleeing the scene.

 

The truck computer says I average 13mpg mixed driving tuned to tow/performance 87, 3" lift and 34" tires. Best I ever got was 17 eco tune highway.

 

going up to 33's ?
Probably don't need a lift. I have the Rancho Q\L and an add a leaf in the rear. I intended on 35's once I wore out the stock tires but couldn't pass up $900 for a set of Wildpeaks someone on here ran less than 500 miles with rims.

So depending on what came factory that's not a big increase.
275/65-18 ( my stock tires) is around a 32.1 ( depending on make of tire and rim width)
so going up to a 275/70-18 is only a 1 inch increase.
weight increase is less than you'd think.
You'll lose more mpg's going from a street tire to a mud tire or some of the more aggressive a/t tires.
I wouldn't touch gears for any tire increase less than a 35. you'll spend more for gears than you would for fuel. not worth it.
tuner - again , tire size increase is minimal.
I went from stock 275/65 goodyears to a set of 275/70 wildpeaks - 21 mpg avg to 19 no tune. I don't drive the truck in a city so I'm lucky with highway/backroads driving.
