Before you throw out the idea of using a wastegate actuator, remember that the spring gives slightly at lower boost pressures. You should try to get a replacement wastegate actuator that will keep the wastegate completely closed until your desired boost pressure is achieved. Your spool time will be a tad quicker like that. Test the wastegate actuator with a bicycle pump and see if it works before you throw it out.

Just cause of the honky that I am, here's the Mitsubishi part numbers for a new 14b wastegate actuator. You can order them from Rockville Mitsubishi cheaper than anyone else around, and you can find their info on-line at www.mitsupartsdirect.com. Sean, Will, and Mike are awesome, they've come through for me a million times getting weird or hard to get parts.
