Nother point is turbos work off exhaust heat.  Superchargers are
mechanically linked to the engine.  So there IMHO is gonna be
alot more fugding to get it right.  I'd lean toward the syclone stuff,
and take a bunch of >bar timing out.  Like I've said plugs are
cheaper than ex valves.

Try for 225 and you'll probably do less backtracking.  What are you
monitoring for tuning?.  
Personnaly never heard of too large of discharge pipes outta a
turbo.  

Use small steps, low timing, rich, and low boost to start, and ease
your way into things.  Hurry this, and you'll find out what they mean
by debit card.
