Our tuning pack brings the 2014+ STI to life making the most of the 2.5 power plant. We replace the stock down-pipe with a Cobra high-flow sports cat improving flow. The stock fuel pump is swapped 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, 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 along with the improved safety functions. Please consider power figures will vary based on engine condition and millage. We spend an average of 3 hours mapping each car.
