Just got a s2 rst and tried to test how much boost it had. it was running only 0.3 so I changed the actuator for a second hand one from a turbo specialist . its out as far as it can go but the car will only go to 0.5 then drops off to 0.4 can any one tell me what the prob could be!!!
I was told it was a new turbo in it which sounds fine and also that its chipped
