[Answering your questions:

1.  I'm no sure how I'm going to do 2.2 bar yet.  Scott Mockry was thinking
about doing a chip, but I don't think he ever got around to it.  Nobody
a pure electronic solution that I know of (i.e., chip and transducer, which
probably isn't feasible anyway), so I'll either do the resistor fakey/big
spring(resistor changes the resistance the computer sees, making it think
the boost is lower than it is), big spring/schrapnel knob (device that
reduces the air pressure the computer sees), or a combo of all three.  What
I'm waiting for BEFORE I go to 2.2 bar is H20 injection.  Car pings a bit
91 octane now at 1.8-1.9 bar, imagine what it will be like at 2.2 bar.  I'm
thinking grenade.]

I have been using combined resistor and QLCC chip & shrapknob for some time
and it works fine when dialed in properly - I have set for about 15 PSIg
and no pinging with 93 octane on even the hottest days.  I'll get even more
once I hook up the extra injector and 034EFI - someday.
