Introducing the all new Road Race timing controller will revolutionize the way that you modify your FIAT 500. The timing controller advances timing by about 3-4 degrees, which noticeably improves HP/TQ, and throttle response. Gains vary from car to car as with every modification in the industry. This timing controller adds horsepower in minutes, and is undetectable by the dealership once removed.  It takes only a couple of minutes to install and comes complete with instructions. We felt no need to add a fuel controller as with other cars we've tuned, because the Road Race Corsa Intake will optimize the fuel curves to obtain maximum horsepower and torque.
