Is the 93 oct. custom performance worth the cash?

mjphillips1981 · #1 Mon, July 13th, 2009, 04:00 PM

Currently my only custom tune is the 87 performance. I have an 07 Screw 5.4L with a K&N CAI and Flowmaster exhaust. I am getting about 14 MPG around town and about 17-18 on the highway. So my question is if I get the 93 performance tune will I get better gas mileage? Will I notice any change in performance? I know a lot of you have said you have seen a difference in mileage with the canned tunes. Any input would be appreciated.

X2 - but naturally I have to add to JHeppner's post!

Virtually every person who's tried the high octane tune has said he got more power and better gas mileage. If that's all you're interested in, fine - go to it.

If however, you are asking will the change be "worth" it, things get more complicated. Power, of course is something only you can judge, and if it makes you happy, it's all good. If though you are concerned about the extra cost of fuel and are trying to actually save money, you have to do some math.

I buy gas at Costco and regular here is $2.23 (right now). I'm pretty sure 91 octane is about $0.22 more. So using the price of regular as a baseline, 91 costs about 9.9% more to fill up. If your mileage improves by at least 10% at these prices, it would make sense to by the high priced stuff. Your highway mileage would need to be 18.7-19.8 to make that come true.

Can you get that much improvement? I don't know. I've never tried.

Thanks for the replies. I love my 87 tune and I can't imagine it getting any better. I just wanted some input from people who have both.

I am leaving for Myrtle Beach tomorrow, it's about 750 miles. This is going to be the first "long" trip that I have gone on with the Gryph. I will post my mileage when I return.

Thanks again!!!

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!

sorry to start a new post but i wanted to put some attention on this...

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