Adding our Tune Pedal P13702 (Picture required), on your petrol 520i 170 hp will make your engine responds more spontaneously and more directly. This throttle tuning system optimizes the response time of your engine by eliminating the latency . The result is that the power of your engine is released faster. This way your acceleration is much more direct. This pedal box is ideal to pass vehicles easily.
Instructions for DIY installation should be more detailled and specific for every single car model. Simple things as intake air filter position makes wiring more difficult in my fabia than in volks.
