For the m45 2.4l supercharger, do i have to go with alky/meth injection with the 2.7" pulley and what kinda of boost level does that pulley give? Thanks

I think it would be very wise too. The sc will heatsoak if run hard and cause a noticable dercrease in power with the stock pulley. The 2.7 will spin it even faster causing it to heatsoak quicker. Alky injection also has other benefits such as keeping knock at bay which will in turn keep the computer from retarding the spark which decreases power.

Most get 6-7 psi as [ion] C2 stated. In cooler air temps you may see more and in hot air temps you may see less.
