EPMAN Sport Manual Boost Controller Kit, designed to increase and adjust turbocharger boost pressure between 1–30 PSI. It operates by introducing a calibrated air leak or a mechanical restriction into the vacuum signal line, delaying the opening of the wastegate to spool the turbo faster and produce higher overall boost.Included Kit ComponentsAdjustable Regulator (Right): The primary adjustment valve. Turning the top knob clockwise decreases the pressure signal reaching the wastegate, which raises your vehicle's boost pressure.T-Piece Tap Fitting (Left): Connects inline between your pressure reference source and your wastegate actuator.Vacuum Hose (Center): High-temperature black rubber lines to route air signals safely between components.
