I have ran 5 gallons of E85 in a full tank of 91 on MAP 5 and she is FAST! I have nothing to compare it to, but I was very impressed. The JB4 is well worth the money as a piggyback tuner. I also recommend the Bluetooth module.
I will give this a try, but with 93. I am assuming your truck is not flexfuel? Are any Raptors flexfuel, for that matter?
