light problems

[ECU5.0]

well its not really a problem...but ive noticed that when im sitting at a stop light and have my head lights on they get brighter when i rev the engine up. the amp gauge doesnt move or anything...but sometimes it looks a little low. alternator tests fine and so does battery...any ideas why it does this. should i swith to a 130 amp alt?

alright...guess im gonna have to shell out some more cash...how much does a 130 amp cost

mine does it too, but actually, mine didn't start doing it until i put underdrive pullies on....i think that had something to do with it

yeah, mine has pullies also....thats probably why it does it.
