Default Problems with pressure coefficients

Hi guys I am modelling a flow over a circular cylinder. I don't know why I can't get pressure coefficient to start at 1 (at the moment it is at 1.25). My y+ value is 0.04 which is pretty good. Is there anything I have to watch out for?

Best regards. Khoa.

did you set the reference values correctly?

Thank you for your reply.

I set the reference velocity to be inlet velocity.

My goal is to optimize our model by varying closure coefficients. C_p close to 1 for some sets of closure coefficients but it can be 1.2, even 1.5 for other sets of closure coefficients. I've got no idea why this is happening.
