Now, this is my first cosworth so i am just learning at the minute today i put all the parts on wound the actuator in took the car out for a spin and when it was hitting around a bar of boost it was spluttering now i thought it would at least hold around 19 psi {1.3 bar} but i am obviously wrong. can anyone shed a bit of light on this situation as all parts came off the same chap who had them on his 3dr. do i need to take the car to be set up any advice would be really appreciated. cheeRS
