New Voltage Regulator at 15V?

I put in a new engine wiring harness and when I took the voltage regulator off the firewall to clean, I saw the potting compound was melting out. Got a new VR from NAPA and when the engine is running, I'm getting 15.05V. Seems a bit high?

On the good side, the ammeter needle is steady and in the middle. Memory says the old VR usually ran low to mid 14 volts (14.1 - 14.6) and the ammeter was always bouncing on the charge side. Voltage was definitely not as stable as the new one has it. I didn't know it had an "issue" so I didn't check it before everything was torn apart.

So, is 15V going to be OK or should I take it back for another one? Any recommendations on a good VR that works as it should, doesn't leak potting compound, and doesn't cost an arm and a leg?
