I get around 14 in town. Last week on a 2 hour highway drive I got 19 mpg avg. No complaints here.

 

I was wondering, if my EGR valve is sticking how bad would that affect mpg's?

 

On what, a 6.4? Why do you think it's sticking? It could severely effect the way the truck runs, but this really isn't as big of a problem on the 6.4's as it was on 6.0's.

 

You can do an EGR valve blocker plate with no problems, provided you have the tuning to match. You can NOT delete the EGR coolers however, without doing an external gate. Well... you can, but you wont like the outcome. The EGR coolers serve double function on the 6.4 as the wastegate.

A hot tuned 6.4, with a single turbo kit and external gate would be a really awesome daily driver.

 

Mpg's havent increased what i had heard other guy's have. It smokes sometimes and does not smoke others.(under like driving conditions.) and yes it is a 6.4.

 

Did you update your programmer?

I have heard and read about the egr being the waste gate. DUDE you don't know how bad I want to do a big single TURBO! I dont drag race this thing or sled pull,so don't need all that boost an the low end. I think it would be great pulling a trailer down the highway.

 

I have not done the DPF delete yet, I am getting 13 to 14 combined where I live. Mostly city like driving, I get her up to 60 and then have to slow down again. She is still under warranty and I don't know if I want to do the DPF delete while still under warranty, don't know how hard it is to put everything back on if I have to take to Ford. Wonder if I should just take it to the Diesel mechanic that changes my oil and stuff and say screw the warranty.

 

that bully dog tuner already voided your warranty. might as well do it right

 

What tunes do you have on it? Are you running the hot damn 300 tunes or the standard 0,80,160,250hp? Do you have a air intake? Any codes?
