Just put in a new fuel pulsation dampner and o rings in and replaced the vacuum hoses.
After driving the car I get no boost till 4500
rpm,s and have checked the vacuum lines a few times

I changed the double throttle control solenoid with a "spare" when it broke but I think they are interchangable.
I can hear the first turbo spool,so its a control issue of some sort,it makes a fluttering sound until the second turbo comes in and then it takes off as normal.
Any ideas anyone?

You get 0-0-10? I thought you needed at least 8psi on the primary to get anything moving on the secondary? What is the exact boost pattern?

Fluttering sounds? Like grinding? or like air? Need more info!

 

Yes pretty mutch 0-0-10.
It sounds like it wants to spool but something is restricting it,definitely a muted compressed air sound untill 4500.

 

Intrestingly there is not any vacuum escaping sound in the pressure chamber when I pull the hose off,the primaries need the the vacuum to prespool properly.

I put a used one on and possibly there is a leak in it so I,ll put the old one back on that just looked bad,and see if this solves it.
