I think that it has more to do with the dyno than your engine. Have you seen other graphs from the same dyno? Any different?

Good numbers!

Same thang trevr said, possibly the dyno or the dyno test procedure they used. I don't think it has anything to do with your engine. What mods. were used for the readings?????
