Lights flicker/dim at WOT

I've noticed recently that my 99 GTP at WOT all the interior lights and when its dark my headlights as well will dim and flicker a bit.. Is it nothing to be concerned about or do I possibly need a higher output alternator or something? It just seems kinda strange to me.

What have you done that makes you think you need a better alternator? These cars didn't have this issue from the factory, so likely time and miles have had an effect. Start by checking the grounds and your battery connections.

The cars completely stock to my understanding. I'll check what you said though.

Perfect, I thought it probably was. Therefore, there's no reason why it shouldn't still perform as a stock car. Meaning, you don't need to upgrade anything, likely you need to clean and maintain a couple of things.

This is true haha. I'm new to all this stuff so I had to ask lol.

It's all good. ask anything that comes to mind on the subject.

My battery connections seem to be fine.. I've noticed they dim right at the shift point from 1st-2nd. Could this possibly be linked to my possible BCM issue thats causing my alarm to go off all the time?
