I have contact details for the guy that designed the Powermod that I used with some success a while back . He would like to develop it for the S2 but needed a donor car . He might work with you if you were willing to do the trial and error part .
Unfortunately he is in AUS though ...

oh yea --you can use the by pass valve to control boost if you want
3 ways of doing this
to control boost with a supercharger there were 3 main ways to do this:
1) install a restrictor in the air inlet. This will reduce the CFM's and cause the supercharger boost to be less
2) install a BOV after the supercharger but before the MAF/VAF. this will bleed off the excess air, but still have the supercharger move the same amount of air
3) install a waste gate in the air inlet section. make the "vacum" seen from the air outlet, and when it goes above a certain amount, to change the waste gate to make it so that the CFMs are les, similar to #1 but can be adjusted just like a normal turbo
help any

How about just using a boost controller. Make the bypass valve into a waist gate, just only for air, not exhaust obviously.

Yes and no. I'm not trying to do that for efficiency, I'm doing it as a tuning aid so I'm totally safe while I get everything setup properly such as the management and other things I'm changing. Crawl, walk, run bro.
There's an update on the 09 harness buy the way. If you remember how the ground wire coming off of the coils had that funky looking junction? Well Mazda did away with that. Now they have every one of those running to direct ground. I haven't checked but I think since there separate each coil is grounded to the same aluminum housing matching the coils either front or back. Interesting!!!!!! Note to all, do this, makes total sense.

I am replacing the entire interior wiring harness---i found a few places on the old that needed attention, and with multiple areas --this stuff--dont repair--replace and I wanted to go through everything.
While I am at it I am running 2 --4 gauge battery grounds (both sides of the dash frame) and daisy chaining it all the way back to the fuel pump.
