ok i have noticed for a month or too that the cav seems to be looseing a couple of psi on full chat it is pushing 14-15 psi and when it gets to about 4000 rpm upwards its droping to 11 ish psi any idears wot it could be ?

i have been told its the actuator but are these avalible as new items on there own or do i need a complete turbo unit

either weak actuator or your fuel isn't turned up enough, simple way to find out is turn the fuel up.

Probably a weak actually.
Mine would only make 19/20psi with the actuator shut and fuel all the way up

[Balley]

mine was like that until i removed the white ring, she will now hold 25psi all day long
