Boost Level on Dyno

Does this graph look correct?

The boost increases from about 13 psi at 3300rpm peaking at 15.65 psi at 4200 rpm then falling at 4700rpm down to 12 psi at 6500 rpm.

if you want to hold more boost up top ask the tuner to control the bypass valve.

Does it need to be done in the TCU or ECU?

I am not getting very far with this, the tuner does not seem to think the bypass valve can be controlled (which means he does not know how) can anyone point me in the right direction so that I can guide them to the right place!
