Yeah the actuator arm is tight as hell, could barely get it back onto the wastegate. Clean on boost, only smokes if it bogs. Can't seem to get the idle much lower but i'll try again today.

Here's another thing though, the car has no cold idle cable attached at the minute. It idles at about 800rpm when first started though then jumps to 1000rpm after a couple of minutes and stays there. Can't figure out why as the idle arm isn't moving when it does it. Fuel filter maybe?

I had a similar problem with the idle jumping up after warm, mine was the throttle cable would get warm and stretch slightly, what I did was move the metal clip forward a notch on the black plastic cable adjuster.
