no bosst on sierra cossie???? anyonew help please guys
Could someone please help,i hava a k plate saph with no boost whatsoeverShe seemed to gradually lose the boost over a couple of mths,in the end with the actuator wound up she was struggling to hit 9psi,and would drop off to as low as 6psi.I have changed the Turbo/wastegate,new Samco hoses,put a live to the Amal valve to check if it clicked-it did.Oh the Actuator is new also,temp sensor has been replaced,charge-air sensor,belt timing has been checked,I have been enquiring after a map sensor,and hopefully will get one for next week. I really am running out of ideas,so if anyone could help me in my hour of need,i would be greatfull with any suggestions.thanx

Well a bailey one wont have a split diaphragm so that bits sorted!! Other than having a split or hole in the circuit somewhere (hoses, intercooler etc). You could try setting the actuator rod length so that with the wastegate closed you can see half the diameter of the spigot through the rod loop if you get what I mean. and then bypass the amal valve by looping the pipe from the turbo compressor housing, straight to the actuator.
