If you are getting less boost than before, it sounds like you either have a leak somewhere or it's not installed properly. Quote Link to comment Share on other sites More sharing options...
ballsoutracing Posted March 12, 2005 Share Posted March 12, 2005 Sounds like its on the wrong pipe, also think a pipe needs to be blocked off, but don't take my word for it, somone who knows wot they are talking about will be along to sort u out soon im sure. Try tightening it as well. Quote Link to comment Share on other sites More sharing options...

neilg Posted March 12, 2005 Share Posted March 12, 2005 i put a controller on a old rover turbo i used to have. Put it on the wrong actuator pipe and it did exactly the same as your getting. I know ballsoutracing said the same but cheak again. You will get it sorted Quote Link to comment Share on other sites More sharing options...
uksupra Posted March 12, 2005 Author Share Posted March 12, 2005 ok looked at some diagrams on mk4.com... they show the actuator for the wastgate having two vacuum hoses running from it... one from the vsv and one going off into the engine... cant see where... do i place boost controller before the actuator inbetween the vsv and the actuator or do i place it between the vsv and the second mentioned pipe running into engine bay???

ballsoutracing Posted March 13, 2005 Share Posted March 13, 2005 This is where I would be lost, but it defo sounds like u have it attatched to the wrong side / pipe, that would give you boost like u are getting and adjusting the controler makes no difference. I looked into this at one time when I was thinking of putting one on, think you need to block one pipe. Quote Link to comment Share on other sites More sharing options...

Hi Mate, I believe you place it between the turbo (engine in your description above) and the actuator. You should have the hose going from the turbo into the MBC, then into the top of the actuator. You then block off the hose going from the bottom of the actuator to the VSV. (You need to make sure the MBC is the correct way around as well). only tighten it a bit at a time or you could seriously knacker your turbos.
