I have a quick question of wha tunes to order. It comes with the canned tunes of tranny tune, 89 octane performance and 91 octane performance. I never tow anything, but want some mileage and performance increase. Fuel in my area is usually 89 octane with ethanol, and 91 octane. Should I order custom tunes for performance for those octane levels then? I have no mods, but plan on a different cat-back system this spring. What would be my best options? Thank you, Jumpn.
I guess I really don't have to decide my custom tunes right now, do I? I need to wait to see what my Hex code is. No sticker on my door. I can get my hex code when I plug my gryphon in, then order my custom tunes when I'm ready, correct?
