MAP drops as revs increase

Hello. I have an issue with MAP values decreasing as the revs increase on WOT. What can be the cause for this? Can this be due to a leak or something?

This looks pretty normal. It will never read exactly atmospheric pressure.

thx for the fast reply.So it shouldnt at least keep constant the MAP pressure value(ex. 98KPa) through out the rev range ?

It will never stay constant as the efficiencies change at different rev ranges and depending on how well everything flows the air.
