your supose to take teh c clip out and adjust it that wat anyhow

with just twisting thebar it wil damage teh diaphram inside

what you need to do is

undo 11mm nut

take c clip out

pull actuator off and adjust and re fit reverse order


but when you re fit it you will need some good grips as it will have to be pulle donto the penny wastegate

good luck as they can be a pain half the time
