datman Posted May 5, 2008 Share Posted May 5, 2008 I just got my Greddy Profec A installed at it works a treat! I have seen some posts around saying there had been problems with this unit. I have a dual port actuator which I set the base pressure at 7 psi. I connected the controller to it as you would an external wastegate (dip sw1 set for external) I ran a vacuum hose from the manifold to the first port of the actuator (one nearest the front of the car) I ran the hose from the valve unit (port under the letter G of Greddy) to the other side of the actuator ( one nearest the wastegate lever). I connected the port from the valve unit (under the letter E of Greddy) to the boost port on the turbo and T'd the port on the valve unit ( under the letter Y ) into the hose that runs to my fuel pressure regulator (from the manifold). After doing 2 pulls in 3rd gear the unit was ready to use, I set the bost level at 7 psi and it held all the way to 6k, then tried 10 psi and then 14 and it was rock steady. Seems like a good little unit which can be picked up for a good price off ebay. like this but imagine the external is a dual port internal profec2.pdf Quote Link to comment Share on other sites More sharing options...
