The power tapering off so early with this dyno is strictly due to the way the car is tuned. This is the firs dyno (out of about ten) where the power starts to fall off. VVEL is the reason boost falls off a bit, but as long as power is going up, there is nothing to worry about. This is straight from one of the best tuners out there. I think this tune is simply very conservative in the upper rpm's, and a bit aggressive to start with as the torque is high. Of course each tuner will have a different power/torque curve. It is like a signature, despite the fact that both engine and turbo kit are identical.
