Air Leak On High Boost

[Scott-EP]

I'll try my best to explain this clearly lol

I'm still running standard Boost by the way...

Basically on low boost the car is pulling/boosting fine,

But on High boost just as you get past the point .6 bar that low boost is set to i think, I can hear a hissing and it doesn't boost any higher then what it would on low boost,

I'm going to put my standard recirculation valve on and see if it's cure's it, but most people are saying it's probably my actuator, But to me it sounds more like it's just leaking from the BOV

Has anyone else had similar problems ?

have you got a boost gauge in your starbo? if you have you will be able to see if its losing boost

if not get someone to rev your car so it boosts and put your hand round all the joins in pipes on the turbo system and around your BOV and see if theres any air leaking. if not id invest in a uprated actuator cause the standard ones dont hold boost as well lol
