H&S Street Mileage

[zack birge]

So here's my situation, I bought my truck back in April. Was averaging 18-19 easily. I tuned and deleted it and it seems the max I can get out of it is 15-16 lately. I've tried different tire wheel combos and nothing. I'm wanting to hear experience with mileage from running the street tunes. I have only been running the race tunes and was thinking about putting my factory exhaust on and going back to te street tune.

Sounds like you got a lead foot. After H&S I saw mileage improve by 1-2 mpg. After I put on lift and 37s I'm now averaging around 16.

Not really, I drive pretty sane. I have a 45 mile commute each way. I just want to stay around the 18 range. Not 15-16. I've bought custom tunes from numerous companies and basically washed my money away on them. None have helped at all.

Are you going off the lie o meter? And not trying to be an @$$ but your driving a 3/4 ton truck and complaining about mileage.

But the mileage going down is what he is saying. Typically when you tune/delete these trucks, mileage increases.

OP: My dad has been complaining about the same thing with his 2011 after I convinced him to delete it. He has only been going off the dash though.

I'm wondering if changing the tuning is changing the dash number or a calibration.

My normal street driving actually gained about .5 MPG hand calculated.

Highway was roughly a 1.7 MPG gain.

35" Tires on 22" American Force Wheels

Cant complain, my 13 is a heavy truck

Ive got a few pounds on you buddy haha.

Traction Blocks, ALA's, and full Trussed Front & Rear Axles with Dual Race Runner Shocks Up Front and Piggybacks all around start to add up the pounds quick!

Whats a set of OUO front and rear trusses run? Have had some interest on them but didn't see anything on RCD website

 

[zack birge]

No my stupid dash readout is always wrong. I'm going off of hand calculations. 3/4 ton 1 on or 1/2 ton whatever. I was gettin old mileage now it's less that's my point. Being a 3/4 ton doesn't matter

 

[zack birge]

I'm trying to swap out my 22's and 35's for some stock tires and wheels. Maybe it'll get back to normal. I've lost quite a few miles per tank lately. I think I'm going to put my factory exhaust back on tonight and run the street tunes for a while.

Ill quote it out and send you a pm, you want the race runners out front?

 

[bricewise]

Yes

Mine gets kind of dismal mileage too (15ish), but I think it's the 13" wide heavy tires causing it.

My truck has 20" BMF's, 35" Toyo's, Icon 4.5" lift with 4 link and OUO traction bars. Me in the truck and 1/4 tank of fuel weighted in at 8100lbs. I stay around 15 with a heavy right foot. If I set my cruise at the speed limit it will stay around 18.5-19mpg.

 

[zack birge]

That's what I wish I was getting. I baby mine to keep it between 15-16

 

[drunk on diesel]

Just drive the thing and enjoy it. How much fuel could you buy with the money spent on multiple sets of wheels and tires?

Just realized yours is a 2013 so you are prolly running the new H&S tunes 6.7.31. There has been some complaints about the new tune feeling slower and getting worse mpg. I read some where that H&S is coming out with a 6.7.32 to eliminate these problems. I never loaded the .31 tune cause I read that some didnt like it and wanted to go back to the .30 tune. I am still rockin the .30 and like how it runs. Do you have it turned all the way up to performance?
