In your opinions would it be worth an 87 tune? We only have 87, 89 and 91 here. The kick in the pants is that 87 is 5.60 per gallon. I don't even look at the 91 prices as I can't justify it as my daily driver which gets lots of miles through the week that I like to play in.

Holy shit $5.60 a gallon. You guys need to drill some holes in the ground up there!

gas prices and fuel mileage normally don't bother me, but I wouldn't daily drive a raptor if poverty 87 octane fuel was $5.60/gallon

When do you guys switch tunes from 87-89-91-93 and why. is it just for when you fill the truck with that gas. can you have the same tune all around and what flash device is everybody using. I plan on buying from mike but just don't know what tune to get. was thinking 89 for performance,econo,per/tow then a performance 91-93 with the livewire ts 5015 flash device. What you think. Thanks

What impact are these performance tunes having on you mpg?

hmmm, interesting

You will see an increase in MPG's with the economy tunes. If you run the performance tune you most likely won't switch back to the economy because the truck is so much more fun to drive.

Exactly what Locktech said.
If I am going to go see family and take the truck, I will install the 87 economy tune as it is a 600 mile drive. Other than that, I cannot keep the smile off my face with the 91 performance tune.
Yes, you will noticed a difference with the 87 performance tune.
I dealt with Mike and he answered all of my questions and provided me with the best tunes based upon my vehicle.

This 93 is what this beast was made for! Massive power gains!!

Ok, this is on my to do as soon as I get money list....
