I'm on a tried and true E85 tune with Wayno's charts and maf. Worked fine for a month or so.
I fueled up at a new station (Very nice part of town) the other day.
And for the past few days I've noticed a lot of bogging. To the point I was manually downshifting to get power.
Plugged the OFT in this morning to check out what was going on:

After some panic, and with a half tank of fuel still I decided the numbers pointed toward some E20 or something instead of E85. And decided the best course of action was to fuel up with 93 and switch over to a Petrol tune.

So I guessed right.
Still need to go back to that station and ask them if they have any idea what they are selling!
