Not holding boost & Rev hunting..

[Shy19s]

Hi guys, having a bit of a problem.. boost gauge shows it hits 1.3 bar and then will slowly drop down to 0.8... whereas before it would hold 1.3 until around 6k and then slowly drop.... if Im in low revs, and I floor it, it will rev hunt until it hits full boost, but still doesn't hold it. I've checked all the pipework, and it seems fine..

Can anyone diagnose what this might indicate.. Actuator? Boost solenoid?

Thanks in advance!

no body has any idea what might be the problem?

Mine does this too shy, but only some times.

I'd be INCREDIBLY surprised if your ko3S ever mananged to hold 1.3 bar at 6k though, even 0.8bar at 6k is fairly good.

We must meet up soon dude, I'm in basingstoke now, so nto far from you
