I'm not just giving the answers away - took me long enough to figure it out.
Essentially you need to devise a way of of being able to limit the boost until a certain RPM, not produce too much boost whilst cruising causing high temps and pumping losses, but still being the least laggy as possible and being able to control the boost at high RPMs - all the while remembering that more boost on a VNT turbo is only a measure of exhaust manifold restriction, you have to balance it quite finely or you'll end up running into a loop of more exhaust pressure = more inlet pressure = more exhaust pressure, overheating everything, but yeh mate i gotz 60psi of boost... I accidentally found out that yes, my GT2052V will happily pin a 60psi gauge, but still not go anywhere.
But yeah - Multiple ways of doing it...
