ATT Update

[6.5L]

I may add fuel but when I first got the truck I was getting 22mpg and 20mpg highway when I was in the throttle hard a lot. I turned it up 1/4 turn once and went down to 19-20mpg if I wouldn't get into the throttle hard. If I did it was around 17mpg. I am afraid to put more fuel in athe cost of mileage. I am 120 miles from home and during the summer I drive 35 miles for work everyday, 70 miles a day total. I would love more fuel for power but I'd hate to sacrafice the mileage over it. I drive mostly highway.

Was that with the factory turbo? Turning up the fuel and boost did not affect my loaded MPG. Never ran unloaded to measure that.

Yeah. That was with a factory turbo, unloaded

Hey 6.5L,

Have you had a chance to get your ATT back on there?

 

[6.5L]

Not yet. I am waiting for it to ship back to me. It's on it's way
