Hi, I'm having problem with boost....will only go to 0.9 bar no matter how much I adjust actuator. I have even had the pipe of the actuator and tried and still the same. Wastegate seems fine and the rest? Amaal valve has the standard jet in compressor side and I have the restrictor pulled out the other port. This has only just started after a turbo change....the actuator still has plenty of resistance.......

 

Aye so what is the correct pipe to use, as this it seems can be the problem?

 

There was a post recently where someone was trying to get boost with the car on axle stands. Hope this is not the case here?

 

Lol....no! Cheers

 

Thanks but it the size of hose I'm needing....inside diameter

 

Err, measure the actuator & amal valve connectors, think they're about 6-8mm aren't they?

Is your amal valve clicking with key-on?

 

Did you change to bigger or smaller turbo? Are you able to run more boost then this or just comparing to what you had before? The last would be a wrong thing to do...

 

too smaller hose id will act as a restriction. I think its around 8mm id. you can use hose connectors as a makeshift restriction inline to help you setup if you haven't any jets. I wouldn't keep winding up the actuator until you find out whats going on with the amal. is it piped up correctly? and is it working (it should click when you turn the ignition key). also, make sure your pipes are piped up tightly as a leak will cause similar symptons. sometimes a small leak will allow say 7psi then not boost any higher as the pressure is too much for the leak to cope with. also check boost hoses are tight and intact
