E85 Tune????
I'm about to pull the trigger on a Gryphon but I got a quick question. I'm got an 07 FX4 FFV. So far I know I'm going with the 87 performance and a tow tune, but how does the E85 tune compare to the 91 tune? I wouldn't run either all that often, but would like to have a little more fun once in awhile.
