Can I adjust voltage output of the alternator on my 3800?

Ive got a new 140 amp alternator on my 3800 project(98 camaro pcm). Its charging around 13 or so but would like to boost that a bit to 14?

Thanks

finally found a thread on it and I guess no. so oh well

If you have a good company near you that rebuilds alternators, you should be able to get them to slap whatever voltage regulator you want on one if you buy it from them. In fact every $400 "competition grade" alternator advertised in stereo magazines that I've actually seen in person simply do just that, after all they still have to fit in your car. For an alternator you already own, no real options but hey look on the bright side that still sounds like a pretty good (brand new) alternator you have to me.
