sorry, not ignoring you, just a little busy this week ;)

hope that helps a bit, basically, there are knock sensors in our cars, the pcm pulls timing to prevent knock (detonation.) to keep you from blowing up your engine.

You can grab a used LS1M (palm pilot) scanner for about $100 used that will scan for KR, and other things, or gauges like these
http://www.aeroforcetech.com/Interceptor_general_info.html that do the same thing.
IPWs (inj. pulse width) is also very important to monitor when dropping pullies, you dont want to max out your injectors @ say a 3.5 pulley, and then add a 3.4 pulley, you'll run too lean and bam, no more engine. (the pulley sizes were just examples) IIRC the STOCK injs max out around a 3.4", but let me see if i can find some more data to support that before you worry too much. Also if you dont have a proper tune for your pulley, you can run into a whole other set of headaches, aside from just not maximizing efficiency.
