That'* the problem. Thats the exact same mistake I made. The TB MUST be before the supercharger or it won't work right.
The TB will limit the amount of air the blower can pull in. With it AFTER the */C, the */C has full access to all the air it can pull in per revolution, which is far to much for idle and low throttle. Also, your MAF is reading all that air being pulled through it that isn't making it into the engine because the throttle plate is closed.
I made the same mistake and it would run like crap because of that. Simply move the TB to PRE blower and make a flange to mount where the TB was and run the pipe to that.
SHould solve all your problems. Even though you have the BOV/Bypass, it is just way to much air moving through the blower rotors and blowing back at the maf, etc. It just makes it horribly bad and your pipes are under more pressure than you think. it isn't like a turbo, the turbo can bypass all the exhaust down the exhaust pipes and relieve all pressure.... with nothing to limit the air the blower is pulling in, even recirculating what it does pull in will cause such an air mess in there it isn't worth it.
If moving the TB is too much work, buy a spare to mount before the */C and pull the throttle plate out of the one on the intake itself to allow all air to just enter the engine. It'* a cheap way to make a flange :P
Hope this makes sense.
