hello all,

just curious as to what mods some of you guys have and what MPG you are getting with said mods..

as it is now, i get 17MPG while putting 340 or so to the ground.

interested to see what you guys get! thanks!

 

I think you are a little generous with your hp assumption.

You mpg seems average for a stick or tuned truck without a lift or big wheels/tires. That's what kills he mpg on these things.

 

2013 EcoBoost 2WD with 3.31 rear end

- Unleashed tuning custom 93 octane tune
- BOSS Coilovers and rear shocks (raised truck almost 5" over stock height with tires)
- 305/55/20 Toyo AT2's (73lbs each)

My commute each day is spent at 80mph for about 15 miles and then stop and go for the other 10, each way. With the tire correction done with the tuner and doing hand calculated MPG, I get as follows:

Tank 100% commute - 15.5-16.5
Tank 50/50 normal highway speeds and regular city - 16-16.7
Tank 100% highway - 19.5-20.5

Everything before the lift and tires was about 1-2mpg higher than it is now with the heavy tires and 5" of lift from the coilovers and tires.

 

yeah i'm definitely on the stock tires so i'm not experiencing any loss from that. also, not quite sure why you think my HP# is an assumption considering iv'e had it dyno tuned. in reality, the truck dyno'd 337 to the wheels exactly. this was inside a humid shop in south texas. the guy who tuned it said it would put down a little more on the street when you factor in real time wind speeds. so trust me, no assumptions here i mean unless you want to say i assumed i would gain 3 hp on the street

thanks for the reply !

 

SCTX4/5* 91 octane performance tune, on 93 octane gas. I've no idea what my hp is, other than it'll run great.
I lost about .5 mpg when I installed the TT mirrors, and another 1.5 when I went to 315/70/17 BFG KOs. Yes, my speedo was corrected.
Now, with driving back and forth to work, 35 miles, 60 mph, usually on cruise, all rural, no traffic, I'm down to 16.4 mpg.
Other mods in my sig that "might" have affected mileage, but it wasn't noticeable to me when I did them.

 

mid 14's stop and go/bumper to bumper city driving, high 17's/low 18's city/freeway driving.
Details in sig.

Also running 91 perf 5 Star

 

Stock is 290 or so - 50 hp gain is a lot due those mods. So either. Generous dyno or those mods made impressive gains.

Regardless though I think your mileage is on par with others stock or modded.

 

How do you know what mods he has?

 

The details of OP's truck are in his sig....

 

Is that viewable on mobile?
