What temp thermostat are you running? The system is designed around a 195 being installed.
When you installed the new core, did you seal any gaps around the edges? Any air bypassing the core lowers the output temps.
Check the flapper cable adjustment behind the glove box (The hot/cold slider). If it has slipped you wont get full heat or cold.

If the spare setup is standard, only the eyelet nut is holding it in place. It just falls to the ground. Can be a PITA to get back in place.
