Pics of the dyno graphs?
Unsure of his "adaption will gain power" idea. On petrol engines the self-adaptives adjust for economy and emissions, as well as driveability, by monitoring the knock, lambda and other sensors to trim the fuelling and timing. It isn't there to gain power unless you're using higher-octane fuel which it can get an advantage from.
From what I remember, mJets don't have as much adaption (only recently they've started fitting lambda sensors, but even then they're only really used for monitoring other areas), and what there is would only be for economy and driveability- it wouldn't boost power. Funny how that 10% future gain to your 165bhp would equate to the 180+bhp he promised.
