6.0 Fuel Mileage decrease

Understandable 6.0 do not get the best fuel mileage. I have '04 With juice attitude, s&b intake, 4in turbo back and fuel mileage went from 12.5 down to 11..im not heavy on throttle..

I do have an 8in lift..understandable that not going to get any fuel mileage with that but even with the lift i was consistent 12.5-13..i just had new head studs gaskets new turbo new cooler new water pump all put on within last 1500 miles..

any suggestions?

Also check for cracks in you uppipe or Y-pipe.
That is why mine dropped do to loss of drive pressure for the turbo.
I had lost about 1-2 mpg.

Get rid of the Juice and get an SCT. The Edge tuning products are known to eat transmissions.

When you had all that work done was your truck updated with the most recent flash?

I will call the dealer and ask. What flash should I be looking for? All of work was done at the dealer under my extended warranty. I will check the Uppipe and Ypipe..dealer Should have caught it if it was cracked considering they had all of that off. My tranny was gone through by previous owner had a billet torque converter put in it and have the paper work!

Thanks guys for the guidenance..
