Why not move it with vacuum / air pressure differential, like the wastegate
controller?
What are you adjusting for? Changing rpm? If so, perhaps an automatic
adjustment could be made.

As for leakage, remember this is related to time. The pulse is very fast,
and the leak would be very slow. In an NA system a slow leak probably
wouldnt matter. But then, a turbo is pressurized...
