Is the 93 oct. custom performance worth the cash?

[PhqChevys]

I have Bill's 87 performance tune, and his 93 performance tune. my truck is very simmalar to yours, it's a '07 f150 xlt supercrew 5.4L 4x4. I gain about 1-1.5 mpg with the 93 tune over the 87 tune. not a huge jump in mpg but its something. but, in return for running 93 i get way better performance out of the truck. i mean like night and day differance in performance. when i got my tunes, i ran a couple of tanks of 87 to try them out, then i ran a tank of 93 to try that tune out...i've been running 93 ever since...
