Steve brought us his FR-S with some bolt-ons for a little bit of ECUTek tuning love. The midrange gains we were able to make were incredible, and goes to show how much power there is left on the table once you change the headers on the FA20. We were also able to find some strong gains up top thanks to the 94 octane fuel and more time fine tuning the other multiple variables the FA20 has to tune on, like DI/Port Injection balance, intake and exhaust cam timing, ignition timing and fueling.


Please note that we have recently had our dyno software updated and the calibration appears to be 5% low. All of our previously dyno tested vehicles open up showing 5% low in the software, so the power graph attached is 5% lower than previously posted dyno graphs. This will be corrected shortly.
