yea tell me bout it its weird how it was running fine til my m8 changed the turbo and since then its not been rite i found out that the reason the boost pipe was collapsing was be coz he had the wastegate constantly open ive sorted this and its stoped collapsing. on the amal valve the pipe that faces straight up wot does this go to and also below the metering head there is some thing to do with the fuel system but it looks like there is a pipe that should go from this to the metering head
