TTFS S55 M4 Remote ECUTune

We look to offer our customers the best performance tune on the market. Through careful remapping of the factory ECU, various factors such as ignition timing, fuel delivery, and throttle are reworked to create unparalleled performance. Our tune has been both dyno and track tested on our in-house M4 to ensure the most reliable software upgrade for our consumers. We highly recommend colder plugs for your S55 motor to avoid misfires under load for the most reliable power.

 Key Features:

• Higher torque over factory settings through RPM range
