I have no idea, I needed a SMIC (since I don't wanna advertise too much, no FMIC) and it was available, so I got it. better than stock SR, better than stock CA, presumably
I figure its plenty for now, since I'm going to run stock boost for now and not much more than that anytime soon..
I also have a 5Zigen SR coldpipe that I'm going to modify to fit if possible.. and the stock coldpipe, OMG so small by comparison..
