how big is the box ? Have you tried it with a at temp load ?
-18 from a MD200 in high ambient could be a big ask
The pressures sound normal for your ambient

20 psi suction is the CPR setting.
What is the temperature difference?
Is the three way sealing?
Is it flooding?
Is the ball up?
Is the condenser clean?
