I've fitted a new turbo to me erst (stage 3 hybrid) and i've got a strange problem with it makin too much boost! I set the actuator the same as the one previously fitted and only want it to make 14psi for now. It'll do this in 1st and 2nd gear but when i give it some in 3rd, 4th and 5th the boost shoots up to over 20psi! Even when i wind the screw on the bleed valve right in it still produces 20+psi!! Never had this problem before and i was wonderin if anyone can shed any light on the situation???? Cheers in advance.
