Who can help The FRS struggles to hold boost with the standard actuator as the spring is pussy and gets pushed open

Now Rob@SCC has tested a couple of others with better springs but still theres to much back pressure and they get pushed open

So anyone any ideas ?

 

i brought an uprated garret item for mine via Rob, as stated it still wasnt perfect but it did help.

 

kev im sure if your using a boost controller this will override the actuator anyway or atleast until the require boost is achived. So i think the turbos just can't supply the air the engine needs at high revs.
