So I just put a u7151 diablo sport programmer in my 05 f150 and I've never dealt with one before...I programmed it to 87 octane but what difference would it make if I did it to 93 octane even though I don't use that grade very often? What's the best way to program it to get better gas mileage and yet more horsepower?

The premium tune is okay with 91 octane as I was told by them, but I didn't see enough of a difference to justify the premium tune. I run the 87 k&n tune. If you have oversize tires you can adjust nov and tire settings. Pm me if you have any other questions with setting it up.

Thanks buddy...I appreciate the advice and I will get with you if I find some other question

And gear ratio, it defaults to 3.73, so if you have 3.55 it will be off.

What comes in the fx4 edition? Cause that's what I have
