Any help would be great. The first step would be to perform some basic inspections on the valve and try to establish what potential causes might exist (such as a leak or an incorrect spring). Went for ride and only heard a flutter/surge sound. Internal Wastegate Actuator No Clevis (EFR, Porsche, Focus, etc.). The adjustment dials do not turn 360O, they start at 1 and finish. I dont see a valve available for my specific model. Do I need one solenoid for my electronic boost controller, or is two preferable? In order to select the right spring for your vehicle you should take into account the amount of engine vacuum generated at idle, the vacuum dip/spike on initial deceleration, and what style of valve you are using (Plumb Back, Dual Port, or Supersonic).

In most cases these wastegates can be customized to different spring pressures (either higher or lower) at little or no additional cost. The best way to confirm proper operation of a wastegate is to run it on a vehicle. Maybe somebody else will chime in to help you better. This is because the boost pressure being plumbed into the top valve chamber is intended to overcome the boost pressure in your charge pipe, keeping the valve closed. Check that the hose between the e-Boost and the inlet manifold is not obstructed, broken or kinked.
