THis is because the turbo is not flowing anywhere near its limits. Flow limits are always reached at high RPM. It is then that the efficiency will take a hit if you run too much boost. So on our stage 0 maps, we run a fair bit of boost down low to give good torque (as lots of people like to compare torque output on the dyno), and then restrict boost up high as the mods will limit flow and we don't want to push the turbo to inefficiency.
This result is a great result. Max power of 221 kW ATW with only 13.5psi. About 35-40kW more than stock. Stick on some decat down pipes and a stage 2 map to run about 15psi up top, and power should climb to the 240-250kW ATW range.
Cheers,
Adrian

Well its your tune, so I wont argue with you. Maybe its the way it is scaled but it looked as though the power was peaking at 4500rpm?
