A high output alt puts out the most amps at high rmp, what you need to understand is a alt will ''shut down'' at certain temps so when you see your voltage drop its because your enginge isn't spinning fast enough to keep it cool to produce the amps. Yes chevy did make alts to be controlled by pcm only to save fuel. I never noticed mine till i did upgrades to my electrical. If your not using the factory plug your alt is "always" on in a sense. What you should do is use a module it will raise the "charge point" of a alt to keep the voltage up even at idle. When it comes to alt and charging everyone has there own opinion and there isn't a common answer since every car is different just read up as much as you can and see what will work in your situation.
What Mike Singer told me was that when having the smaller pulley, it spins faster when at idle to boost the idle amps.
The problem isn't your PCM, it's because you switched the pulleys.
Ok I'm using factory plug aswell no harness nothing

your problem is not your computer, as your computer will not vary alt output by rpm.
If it is the computer all you have to do is turn your headlights on to bypass it. Most pcm regulated alternator gm vehicles have it programmed in to automatically command 14v instead of 12.9 once the headlights are turned on. I'll gladly make a video with my scan tool, 270a singer alt, and my 05 grand prix if anyone wants to argue that.
