MPG's

[bigsexy6.0]

All my upgrades are listed in my sig but I had the studs, delete, new tunes, and a new FICM unit at the same time not long ago and my MPG's went to **** why and what can I do. I used to get 18 MPG's. Now I get 12.5 lol I love the new stuff but dang......

All those mods should of increased your MPG's! I think you got some new tunes along with a heavy FOOT!!!

I wish that is what i figured at first but it don't matter how I drive... my last tank I drove country rodes at 55-65 and never got over 2100 rpm on take offs and still got 13.... I don't know how to baby it anymore than that lol

[USMC6253]

Don't know maybe those tunes have your fuel turned way up. Or will just take a while for pcm to recalculate the amount of fuel to air ratio. keep babying her see what it does after three tanks. Did you change tire size after leveling kit.

[bigsexy6.0]

yes but only 295/70/18s so nothin 2 big

Did ford update your programing?

It is either tuning, problems from the work done on the truck, or problems not related to the work done.

How is your smoke?
Do you have an exhaust leak from when you deleted the egr system?
How is your turbo performing?
When did you delete your egr system?
How many miles do you have on your truck now?
How is you maintenance, air filter, fuel filter, oil, trans, diffs.... ?

Also, if you said you got a new FICM, it probably has the newest flash, which kills fuel mileage. I have a brand new one as well, and my fuel mileage is awful. But, there is hope.

PHP or Innovative can tune your FICM to get that lost mileage back. This will be my next mod.

how much do they charge for the ficm tuning again

[SickStroke6.0]

$150-$200.

Yeah I think the FICM tuning is going to be my next try.... I don't have any leaks, new oil, cleaned the air filter 3 weeks ago, trans fluid about 15,000 miles ago, hardly smokes at all only if i put it to the floor from stop. the truck runs better than it ever has with more power more boost and cranks great. I just get crap MPG's I didn't know it anyone knew something I didn't.
