Nah you'll be okay for now Ryan, but many stock actuators are leaky (all are quite weak compared to the HKS item) so it's a good thing to replace in the future even IF you don't want to up the boost, as it'll help hold boost better Also, you should be aware the boost may creep (it may rise above normal levels) after fitting modifications that get rid of restrictions, especially in cold weather. If power cuts out and/or the engine management light turns on it means you have hit fuel cut, so it would be wise to turn down boost slightly via an adjustable actuator until you can sort out fuelling (aftermarket ECU or FCD&RRFPR). If you keep hitting fuel cut, the engine can obviously run lean and get damaged!
