This actuator is designed specifically as a direct replacement for the MK5 VW Golf which utilizes the 2.0 litre FSiT engine.

This wastegate actuator, if assembled with the yellow colored spring, which is rated to a base pressure of 10-15 PSI, will increase the boost output of the application to a degree that will exceed the ability of the stock fuel system to maintain the necessary supply of fuel. Because of this, you must use an upgraded high pressure fuel pump (HPFP), and the necessary fuel pump specific software also be utilized prior to the installation of this actuator. We recommend using software such as APR tuning that offers the ability to adjust boost, fuel, and timing settings to best compliment this wastegate actuator, paired with a HPFP upgrade, in order to be able to supply ample fueling.

The actuator can be assembled with different springs upon request. Please contact us directly concerning this process. If this product is purchased with the intent of increasing the boost output of the turbocharged system, we cannot guarantee compatibility, nor the ability to increase the boost output beyond a level that is within the parameters set by the engine-management-system. whether that system is factory or aftermarket. Neither Avenue Autosport nor Forge Motorsport 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.

While Avenue Autosport is happy to supply you with an actuator capable of holding boost beyond that of your factory unit we are in no way capable of knowing nor suggesting that your vehicle's engine or related systems are capable of supporting or surviving the stresses of such elevated boost pressure.
