What mods are done on the truck to get 22mpg? I'm assuming DPF delete and tuner. this is the 6.0 section bud, the 6.4 is a way different animal.

I do know an injector issue on a 6.4 is something you want to fix sooner than later, if it's hanging open you can melt a piston, or worse.

My guess is it needs a new injector there.

 

4 inch exhaust and a kn air filter kit is all that has been done to it.
Igoofed and posted in this category I meant to be in the 6.4 listings. I want to lift it but with my 5th wheel I can't. Thanks I think we will try to pull the injector this weekend, can't wait to price em.

 

Not a fan of K&N here either...

There is a HUGE following of 6.4 guys on powerstrokearmy.com too bud. They can get you answered up quick too.

I've also seen quite a few 08 body styles lifted a little with 5th wheel setups.

 

thanks i will look over there also. ive seen a few that are lifted also but with my trailer i can't get the weight on all 4 tires to balance the load so it pulls right. thanks for the advice though.
