Description
These small switches offer big adjustability. By simply turning the dial left or right until it clicks, you are able to command your truck to give you more or less HP & TQ. This obviously only works if you have already flashed the ECM with SOTF tuning software. Depending on your vehicle, our switch will utilize your truck’s Fuel Temperature Sensor, Crank Case Pressure Sensor, or Intake Air Temperature Sensor.

Returns
Unused parts in original packaging may be returned within 30 days of delivery. Tuners married to a VIN need a factory unlock first — text a tech.
