Not downing their kit at all, but just take it to a rebuild shop and ask them to upgrade it. The alt will look brand new when you get it back for around a $100. The shop I use gets me around 180 amps out of them, he said sure he could get a little more but I'd have spin the crap out of it to get there. So with that in mind make sure it's making power where you drive/rpm range, not just a wot blast.
