Now by doing this, if I were to raise the boost pressure would I need to get it retuned at that pressure or how does this work? My goal is 350+ or 375 if possible. What do I have to do to achieve this? New internals or just increase boost pressure? Thanks guys

The short answer is yes, you can just up the boost (until you run out of fueling.. 450cc injectors are on the small side) and pull timing. You will want it tuned.
The more complicated part is how you drive the car? Are you looking for a trackable 350+ HP? In that case I would look at E85 and/or some new lower compression internals. More boost and pulling timing produces heat, and sustained heat will eat up the motor. I make over 400hp on over 20psi with stock internals on 93, but I also don't track my car. I would almost guarantee that if I tried sustaining that for a few track sessions my engine would be on it's last leg. But for some fun on the highway and back roads it is going on 8000 miles holding up just fine.
