Alt voltage drop w/asp pulley, A4 cars

[shortdog]

The old alternator was reading 14.5 cold and only 13.1-13.4 volts with a warm engine and I was also having the problem with the guages flickering and trip odo resetting itself due to a low battery (99 tsb bulletin). This was before the asp install. Now, with the asp pulley and new alternator, it reads around 14.5 on cold starts, but it drops at around 13.6-13.7 after it's warmed up and running. However, my battery stayed charged at around 12.8. Is this normal for the alt voltage to drop after the car is fully warmed up? For the A4 cars with asp pulleys, where does your gauge read at idle and what's considered acceptable? Any help is appreciated.

Edit: Mods, remove duplicate post. Thanks.

Anyone?

12.8 sounds perfect. Are there any problems or are you just asking if it is right? Everything sounds good to me.

My main concern was if it's normal for the voltage gauge to drop when the car is warmed up.

Sounds normal to me - gauge will slowly drop after a cold start. Mine will even "dip" from time to time. Remember reading some posts about A4 guys bumping up their in gear idle a little after an underdrive pulley install if you have a stereo that draws a lot.
