I don't know about this crap about using "resistor plugs and not conventional", all plugs in any ecu equipped car should be resistor, in fact I can't think of a single engine these days that isn't resistor plugs, emi can knock out ecu's, one of the reasons they are used.
In short just experiment with the gap so long as it sparks under all conditions it is fine.

blown out sounds like they are candles, and is not very technical. and surley all cars adiabatic CR ratio changes as more throttle is applied and more air enters the cylinders! doh! and surley there is more than two compression ratios, surley the compression ratio is constantly changing with the throttle position/boost/air temp/engine rpm. Dont call my information crap about resistor plugs when it is true!
