The red curve is the first run, and the green curve is the second run. For each run, the power and torque got lower. Seems like the fan could not cool the intercooler well enough, causing the engine to regulate the output down. I am guessing that this also happens at high RPM in all the runs here. My sound based measurements from open roads indicate that the power curve stays flatter at the top when the engine can get enough air

I would say that 138 rwhp indicates that the power is more than slightly underestimated...
