So I have a 2015 STI Launch Edition. Currently running Cobb's Stage 1+ Map with their intake and a Borla Catback. I am in the process of compiling parts as I have the extra money that I will be putting on when I decide on a tuner and go get a dyno tune. I currently have a Cobb catted dp, ID1050x injectors and AEM 320 fuel pump that I am very eager to put on. The next step is to buy the Cobb Flex Fuel kit and pressure sensor as well as an ebcs (probably grimmspeed). I have also read online an aos would be very helpful once using flex fuel. I was wondering who else has taken a similar path with their STI, what you think worked, what didn't work, what you wish you would've done, mod lists and of course how much power you put down. Any insight on the flex fuel conversion would be very helpful!
