Minimum 20hp & 22lbs tq gains from the custom ecu upgrade. Our clients were blown away with how the vehicle responded after the upgrade and could not believe how software programming could provide such amazing results. The S500 went from moving like a tank with the restrictions place upon it to moving how it should which is fast, responsive, endless power and no restrictions at all.
Also removing the air flow restrictors helps the car breathe a lot better. To access these restrictors the hood has to be lifted and the intake pipes are located beside each head light. Our clients were removed prior to programming.
Another satisfied customer :)
