This is for anyone that has an Apexi RX6 single turbo with the Power FC. I just had my engine rebuilt with a street port/polish and stock 2mm seals. I have a Power FC with a Greddy Pro-Fec B and all of the necessary upgrades in the fuel dept. (12oocc secondaries with a Nippendenso high flow pump. There was also a mod done to the fuel rail that will allow it to flow better because I have no emissions, what so ever. I am also using an M2 large intercooler with the wastegate plumbed back into the exhaust. I was just wondering how much boost you guys are running on pump gas (93oct) and of course being safe about it, this engine rebuild was expensive by the time it was all said and done. Also what boost do you guys use with say 100 oct plus. I need serious answers only, I dont want to blow my engine again anytime soon. One more thing did you guys tune your car on a dyno with these boost settings or are you using the maps the computer came with.. Thanks a million...
