A compression test only reads the pressure build up between the piston and head based on how well the rigs are sealing, it will always leak down past the rings. your motor is new and the rings may not even be set in yet. compression tester should only register the maximum obtained pressure above the piston. I think you should do a leak down test, that checks the whole crankcase for air leaks, totally different test.
