I would imagine that you would need the VT2-650 software and injectors to take full advantage of a smaller pulley. Im sure just adding more boost to any kit will net some power but there are other factors that contribute to making additional power and doing it safely.
Yeah we hooked up a mechanical boost guage during the initial dyno runs at EAS back in October when I was consistently getting 4.9 to 5.1 psi on the 96mm pulley. The mechanical boost guage confirmed the results. And yes it's very clear now that I'm tapped out on the 625 kit so software and fueling is required to get more power.
