MarkRS,

Been out for a drive and this is what happened.

Removed Actuator pipe.
Set preload to half a hole.
Drove car and as soon as it started producing boost it dies.
When i say dies, the accel is really quick then its as if someone has stamped on the brakes, as the surge just stops.
When this happens ts barely producing any boost.
Stopped, adjusted act. 2 complete turns.
Drove again, no different.
Refitted Amal Valve and it started producing boost again, albeit to low....

So not sure what is going on really.

Any thoughts?
