Our Stage two tuning option for the Impreza STI is ideal for Subaru owners wanting to improve performance for road cars. Starting with the SBR 400 billet turbo we then replace the stock down-pipe with a decat also adding a non resonated center section. We then swap the stock fuel pump for the RCM 340 and remove the OE FPR to fit an adjustable fuel pressure regulator ensuring optimal fuel delivery. Next we add a cold air feed induction kit to improve engine breathing also reducing inlet temps. Your car is then mapped on the road optimising throttle response, peak power and mid range. The map will retain all the factory functions your used to along with the improved safety functions. Please consider power figures may vary based on engine condition and millage. We spend an average of 2-3 hours mapping each car.
