It will be interesting to see what your boost curve and max boost will be with your mods.
MILVs, headers and exhaust will all lower your boost.
Lower boost and more power because more air will go into the cylinder and get out, less 'stacking up' of boost in the intake manifold.

I have a smaller Vortech pulley that can be made to work with a shim washer and machining of the mounting bolt surface shorter. I will look at the needed specs when I get home from work.
