Tuna is on the money. The initial diagnosis was that it isn't boosting past 1 bar, and the solution is to get a new turbo? Wouldn't it be wiser (and more cost effective) to either perform the mod tuna has posted, and failing that, get a decent actuator and see how it performs then?

EDIT:
Just for reference sake, before the rebuild my MY99 was pushing 240hp @ 1.3 with PowerFC, VF30, exhaust, APS TMIC, ultimately similar setup to yours, hence my reasoning for solving your low boost problem before outlaying for a new snail.
