You need to buy a different pulley.
Are you running stock MGT, standalone, or some type of piggyback on your Vortech? Not much to tune w/ the FMU provided by Vortech, although yes tuning to some degree would be beneficial.
This isn't meant as an insult at all, but you do have the SC correct? If so it may benefit you to learn how a SC of this type actually works and why the pulley is the determining factor in your PSi of boost.
Good luck

I've just finished installing a Comptech SC/AC, but even before the install started I was anticipating the day when I'd be use to the added power and want more. I *think* I have a good basic understanding of FI, but I have very limited experience with supercharging, and close to zero experience with S2000 supercharging. In any event, I have similar questions about upgrading my Comptech setup.
On the Comptech system the fuel pressure regulator ramps up the fuel pressure under boost. Parts are available to tailor the regulator to a wide variety of setups, so some tuning is obviously possible. What I lack is the experience to know whether or not the standard regulator setup is also correct for a higher boost pulley. Does the fuel pressure ramp or knee need to be altered? At what point do you reach the limits of the stock injectors? Increasing fuel pressure has its limits, right? How far can we go with a simple fuel pressure regulator and the stock injectors? If I go to a 7lb. pulley do I need to change anything else? Sure, I can do it, put the car on a dyno, and find out, but since others have already been through the exercise it seems wasteful to repeat their efforts. I don't see how asking such questions reflects on one's understating of supercharging, because the questions are application specific.

No my pre-statement was to ease a post like this. I don't want the guy to feel insulted, he has a valid question. Although he is asking what he needs to do to make his SC make more boost, correct?
If he understands how a SC of this type works, then he would get why the pulley is the determining factor in his boost. Then maybe his question would be more geared toward what he needs to do to run higher boost properly as to not create a problem. So w/ a better understanding of how the system works on a whole he can work towards figuring out what he needs on his own and then contribute and pose questions to why something may or may not work.
In reference to his question:
He didn't state what his boost goals were, or what he wanted to achieve. Well besides running more boost. Does he want the thing to make 10lbs, 12lbs...
The question is fairly general. Like me saying I want to go fast.
I'm all for knowledge, especially on something like this that could have repercussions for doing it wrong. So doing the research about what you have currently, will greatly help you on improving in the future.
Hell, don't hold asking anything back because of me... I'm just as lost as all the other sheep. I'm here to find my way.

No need, when I take my own ignorance as a given. 
Maybe it's just me, but I don't have any problem with the original question. As I see it, I'm really asking the same thing. "I want more boost. What's involved?" Just because I don't say any more doesn't mean that I don't know more (does it?). LOL, it *might*, but not necessarily. (Right?)
It could be that I'm just too easy, 'cause I think that the only stupid questions are the ones that are never asked.
