Downpipe option
Our Stage one tuning option for the Subaru Forester is ideal for Subaru owners wanting to improve performance for road cars. We replace the stock down-pipe with a high flow sports cat to improve flow. We then swap the stock fuel pump for the RCM 340 to ensure good fuel delivery. Finally we add a high flow panel filter to improve engine breathing. Your car is then mapped on the road optimising throttle response for peak power and mid range. The result is a greatly improved power band with boost target being achieved sooner and holding for longer across the RPM range. Your 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 and average of 2-3 hours mapping each car.
