Naughty naughty Avi, running that cheapo gas.  Bettery you than me!
I am not suprised you got a little pinging with under those
conditions.  I always carry a bottle of octane booster that I can
use in an emergency, as keeping my foot out of for a whole tank would
prove impossible.  :-) As we left it, after install, you car was running 
pretty darned fast.  

I don't really recommend installing a pop off vavle on a car with a 
catalytic convertor.  You will be fooling the FI system into dumping
fuel into the system and thus down the exhaust manifold, and into
your cat.  A closed loop that dumps back into turbo inlet is
a better approach.  I hope to develope a kit next year.
