Quick question for those who have done any of the E85 custom Tunes from either 5Star or MPT.
Did you see any Fuel Mileage loss/gains? Or did you see more just a power/performance gain?.
2014 3.7L
Currently average around 16.7-17 on 87/88 octane
(The Casey's around me offers an E15/88 octane blend.)
My first tank of E85 I averaged around 15.5.
I just am curious what people have seen doing some of the custom tunes.
I have an SCT X4 with their tunes but haven't loaded anything yet.
