I also highlighted what I believe to be the error in your logic in blue. Could you please explain to me why you believe that a compressor problem, with what you claim to be "perfect pressures" could be causing your problem?
The compressor is pumping, you needn't ask more from it at this point in time.
As requested, please take the requested readings and post back. We'll explain what the problem is and WHY we know it to be the problem from the information that you haven't yet provided.
