If you take the route tas suggested and lie to your ECU about the amount of air by putting a leak in the line(which you could also do by placing a small butterfly valve with a servo on so you could vary it as you chose) then you should turn all the frontal area of your ride into a mesh covered ram scoop. It will lighten the load on the turbo allowing it to approach free-wheel speeds of 150K rpm or maximum boost at lowest possible temperatures at a lower engine rpm(takes less exhaust gases to turn the turbo if it has to do less work to turn).
