I THINK the later 6.0L trucks can but I have seen nothing in the way of gasoline trucks that supports that idea.

everything i've read suggests the PCM actually supplies the field current for the rotor through the regulator, that the regulator itself is merely a "potentiometer" that is turned by the PCM, thats what got me wondering

The alternator can only work so hard without burning up. You could either run the risk of overcharge or having parts burn up. If your current alternator isn't cutting it then you'll need to go bigger mechanically. If you are having trouble at idle you could try to raise the idle speed. Kinda like I can program my truck to rev all the way to 10K, but the mechanics might not survive.

I already have a 250 amp mechman alt but the PCM limits it to 14 volts. I was only looking to go to about 14.5 volts

Is the pulley the same size? My truck will let it go up to mid 14s while driving. Upper 13s while idling.

Finally, your electronics might start to suffer at 14.5 Volts. To see if your battery is charged, you need to have an Ammeter in series on one of the battery cables. If the Ammeter reads near zero, it means it is not accepting a further charge because it's fully charged. At a resting state, disconnected, and with the surface charge from charging worn off, the battery should show about 12.7 no-load Volts if it's fully charged. - Jack |

What are the amps on your battery then? That might be your weak point. If you feel that the stereo isn't hitting hard enough what gauge wire are you using? Also do you have any capacitors wired in?
