Hi all
I have a 2008 f150, crew cab 4x4,5.4l, 3.73 ratio rear end, 2 1/2" hell bent spacers on front and Firestone Destination 285/65R 18 M/T.
I am looking into purchaseing a Grayphon from PHP.
Question is what do you guys recomend?
I am not a Gear Head,( not any thing wrong with GH's) and get lost in all the programing aspects.
I am just looking for help decideing what to purchase.
Should I just go stock or get some coustom tunes?

Thanks
JW

 

What octane gas do you use?

 

85 octane.

 

Then if you'd like to continue using that octane you'll need custom tunes.

Reason?
The canned tunes of the Gryphon are.....
1. Tranny only>>any octane gas can be used.
2. Tow>>87-89 octane gas only but 85 would work assuming that you're are in higher elevations.
3. Performance>>91-93 octane gas only.

So as you can see if you would like a performance tune and keep running the same octane gas, custom tunes will be needed.
