Just a little advice when you get your Gryphon in, go ahead and put in some premium fuel and go to level 3. You won't even want to try the other canned tunes. I ordered 1 custom tune, 87 performance tune, and it is going to be replacing the level 1 canned tune. Reading everyones opinions and inputs over on f150online I was a little skeptical that this programmer could make that much of a difference. After getting the Gryphon though I am a true believer. I have a smile on my face every time I press the skinny pedal
The best part is even though I get on it more now, my mileage has still went up by 2.1 mpg. If I could ease up a little it would go up even more. I can't wait to get the custom tune to be able to use 87 octane instead of 93 though.
