I want a SCT tuner for my 01' 5.4L F-150, i mainly want it for the 87 setting for better MPG, and also to change the tire calibration, cause i put on bigger tires.. also, about whats the MPG increase i should see on the 87 setting?

oh, i emailed Troyer about it too..

 

I run with the 87 tune and haven't seen any real increase in mpg. Remember, these are performance tunes.

 

No MPG increase here running 87 perf tune 99% of the time, just much better performance.
