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...

You say it quite well. You probably pay a little more for gas, but you get your money's with in enjoyment! Sometimes, that's what really counts!

Our 93 over here must be REALLY bad, my mileage went down after switching to 93. Played with the canned 87 tow and my average was about 15-17 even with gunning it a little. When I started using the canned 93 it went to 13-16. I drove the same places and drove like there was an egg under my foot. I also couldnt even get within a second of my 0-60's while using 87. Just switched back to the 87 tow that I played with and gonna see how that goes. If it still doesnt improve then I'll know its the gas.

well guys I just returned from my Beach trip. I ran the 87 perf tune the whole time. I got about 18 MPGs on the way down. I was cruzin' at about 70 MPH. I thought that was really good!!! On the way home I go about 16 MPGs goin about 75 to 80 MPH. My only problem that I ran into was, on the way home i noticed that when the torque converter would lock in, the truck shuddered like crazy. It did this for about 20 miles or so and then went away. Anyone have any idea of what that could have been?

Sounds like the lovely RXDE/RXDG shifting issue. There is in update on the server for you. See if this helps.

Thanks.

I did the update but now my custom tune is gone. How do I reload it back on to the gryphon?

mjphillips1981 - I understand your concern, but please don't start a new thread over this. Bill WILL be able to help you and I'll draw his attention to your problem. I managed to wipe out one of my custom tunes a while back and Bill restored it to me without too much pain om my part (other than me feeling like a jerk for causing the problem). You don't even have to worry about that. Just be patient. You'll get your tunes back.
