O.k so i have a turbo car here not a starlet.

The car has boosted upto 0.8 bar which i have seen on a boost gauge and didnt't want to past that as the fuelign is nto done yet.

It has an adjustable actuator as stock and is full adjusted to the lowest psi setting possible i.e the actuator are as long as it can be adjusted to.

The problem is the arm is not dumping at 8 psi which is what it should be on stock. I have taken the wastegate off and the arm operates properly with i.e move when i put my mouth to the vacuum on the actuator. The flapper valve moves freely. I have noticed that from the gasket the joins the downpipe to the turbo small plumes of smoke somtimes come from it. The vacuum line was changed from the outlet side of the turbo to the inlet vacuum just incase that was blocked but still no change.

What could be causing the problem? It has good vacuum, the flapper valve is not sutck, the actuator seems to function properly.

Any help to sort this out will be great.

my brother blew on the vacuum of the actuator and it moved out and i tried it on a t3 actuator and it didnt budge the one my car is a t25 stock. Is that right should it move with a person blowing into the vacuum

you dont realize it, but you can at most probably only blow 2-4psi (you couldnt sustain 4psi) and it sounds like its a ~10-12psi actuator, so no, blowing aint gonna do anything, try ~10psi from a air compressor, up it a few psi if it doesnt move, if it doesnt move at ~15psi, its probably got a torn diaphragm.
