antno Posted September 4, 2012 Share Posted September 4, 2012 I think I have a problem with the wastegate actuator. At the moment I'm running direct pressure from the compressor housing to the actuator and have blanked of the side that goes to the vsv. It is achieving 1.1 but it's progressive and doesn't get there till 6500rpm. Like the valve is only half open. My vsv wasn't working so i tried this just to see if it would dump all the boost. I have tried 17.4 psi of pressure as the manual says and it seems to be moving. I do have another actuator to fit if it is that. Just wondered if anyone had any other thoughts? My car is a bpu tt6 with ristrictor ring. I have had all the turbo side off. New gaskets throught and new silcoln hoses. I have pressure checked it and all seems to be fine. I'm also not sure if it was working before as I had alot of boost leaks that limited me to 1.1 bar unfortunately. Cheers antno Quote Link to comment Share on other sites More sharing options...
