When you fit a Forge turbo actuator you will be able to fine tune and manage your specific boost requirements, this will allow for improved response and better control. This product is built with a predetermined actuator spring suitable for, or slightly above factory boost levels. The actuator can be assembled with a stronger spring upon request for tuned vehicles, and where a higher boost level is required. Please contact us directly concerning this process. It is designed and built with the intention of increasing the boost output of a turbocharged system. We cannot guarantee compatibility with all applications, nor the ability to increase the boost output beyond a level that is within the parameters set by the engine-management-system of the given vehicle at the time of installation, whether that system is factory or aftermarket

Diaphragm sealed internals are the default selection for this actuator product but customers now have the option of piston sealed internals. Unique to Forge Motorsport, this innovation offers equal performance to the diaphragm type and low maintenance due to the hard wearing nature of piston sealed valve internals.

Forge Motorsport nor any of its authorised distributors can assume any responsibility for any adverse effects resulting from the installation and tuning of this product onto a vehicle whose engine-management-system, whether factory or aftermarket, is not capable of allowing for the desired level of adjustment.
