are you running an underdrive pulley?

No

I have a less than 6 month old battery in mine. I checked yesterday. I was getting 13.7 with everything off (while driving), 13.6 with AC running, and then fluctuating between 13.5 and 13.6 with the AC and the system (about 600 watts or so). Idle voltages are similar, never dropping below 13.3 and never getting higher than 13.7 really.

I've been having the exact same issues/voltage readings as The Spectacle.

I did the Big 3 upgrade and saw no change. I swapped the alternator, no change. I disconnected all extras (HIDs, sound system, radar detector, etc), no change. I even went so far as to have NST custom build me a 20% overdrive alternator pulley for $150, but I ended up not putting it on and just living with the low voltage
