The problem is that VNT Turbos will produce too much air for our engines to handle at lower RPMs...
But having it in full closed position to produce as much boost as possible means that cruising you'll end up producing like 15-20psi, getting things very hot due to high backpressure and causing quite high pumping losses...
You need to be able to reduce the backpressure at low throttle and restrict the boost levels so it doesn't end up surging.
