M400 Overrun Boost

The MoTeC M400 Overrun Boost accessory provides advanced control over boost pressure during overrun and deceleration phases in turbocharged engines. This dedicated module works seamlessly with M400 ECU systems to maintain optimal turbocharger speed and response between gear changes or during throttle lift-off events. Particularly valuable in motorsport applications where rapid turbo response is critical, this accessory helps eliminate lag and maintains competitive advantage. Professional tuners gain precise calibration control over boost behaviour during transitional driving conditions, improving overall engine performance and drivability.
