you can add a correction factor into a dyno; someone could have easily modified those dyno results with a 1.15 or 1.2 correction factor so that it was reading high. as was previously stated, the only real information you can get from a dyno is change in hp, not absolute numbers. and in all the tuning i have seen of boxsters, i have yet to see anyone bolt on a 50 hp increase. i have seen people brag of 300 hp, but no 50 hp increase. that's why everyone always wants before and after numbers, because absolute numbers mean nothing when it comes to dynos.
