I absolutely love my Open Flash tablet!
I flashed my '13 FR-S with the Stage 2+ tune (no E85 because I live in hell) and... it may be all in my head... but I swear my car ROARS now.
I recommend the OFT to everyone who will listen (and owns a compatible car).
When I first bought it, I only had a new exhaust so I was Stage 1. Then, I added a CAI and UEL catless header and moved to Stage 2 (2+ was years away), and now I'm stage 2+.
Each stage brought the same fantastic seat-of-the-pants excitement; like I got an all-new car.
Thanks, Shiv, and the rest of the OFT team - your work is outstanding.
