    turbo question?????

    i was told by a vauxhall astra gtc driver that on the turbo theres like a tiny nut on it and if you turn it gradually, but not too much in one go or it will blow the turbo up then it tunes the turbo and makes it quicker the car - now i dont trust vauxhall astra drivers and ive not heard of that before has anyone else heard of it

    He's on about the actuator, increasing pre-load by turning it up can help with power, but without a map to suit it's pointless and dangerous.

    I came from the Vauxhall (VXR) scene and there is some plebs about.

    The actuator has a threaded rod which connects to the wastegate, nuts are in place either side to retain the position on the wastegate. He means them nuts.
