i dunno man, im new to the mustang world and everything i read on the 5.0 kit was pretty decent. larryb aka stretchb on svtp seems to be having good luck with his kit so far and it seemed to make good power. longevity was my concern, the turbos/gates i had planned to upgrade and just use the piping for the ease of not having to get something fabbed up, but at this point that paxton is looking like the cheapest way to go. im just not thrilled by the lack of torque the centris are making.
edit: looks like he broke in to the 9s tonight on some test runs. granted he has a built motor and the 67mm turbos.
