OP: I have ran ACE and Delicious Tunings Flex Fuel kit on a couple of different BRZs. I can recommend the kit with no reservations. My main concern is that your expectations are realistic. The power difference is noticeable but not a huge leap. However, I have a hard time enjoying a stock BRZ now compared to one running an ACE and E85. The BRZ really feels proper with the FF kit and the ACE. I agree with other poster's that the E85 over 91/93 isn't huge but is noticeable. However, the cars throttle response and smoothness are what really make it even more fun to drive on E85. We all did it for more power, but E85 always seems to make a car feel like its having its best day. All the cobwebs are knocked out. This is not unique to the BRZ, but if you want your BRZ to be the best version of itself while still feeling stockish. You can't do any better in my opinion than the ACE/DTFF combo. I have tried, and failed to find a better set of initial mods.

I have ran a)OFT/OFH. b)OFT/Tomie Header. c)Ecutek/Tomei. Ace is the best, and with FF and Delicious tuning, its a great setup. Out of all the mods I have done to cars, its one of the least likely to cause buyers remorse or cause reliability concerns. I would suggest doing the revision map runs with Delicious, but if logging and etuning is not your thing...you can just run the base map with likely no issues.

I have been through the process 3 times with Delicious pertaining to a BRZ. Its an easy thing todo.
