Where is the ECU reading reading the MAP from ? Under the throttle butterflies or right at the turbo outlet ? If you are reading right at the turbo outlet, the MAP will be more than under the butterflies on boost because of piping and intercooler losses.
I have the same manifold "box" as you but read my map after the butterfly .. I tried both locations and the map at the turbo was 2psi greater than after the butterfly .... looks like my intercooler/piping loss is 2psi
Still wondering why the HP and TQ are the same as your 2 litre
