Can only comment on my own experience but I've never seen that blue writing on mine. I'd contact who you bought it from.
As for power figures I'd be inclined to believe it. Mine once mapped with mods showed 272 bhp on badger5's rollers and on the way home when tested on the gauge showed either 270 or 271.
