[QUOTE="98cobra#1222, post: 15677470, member: 125489"] What Tabres said, actually there is a reduction in ignition system performance at high boost/rpm since the wasted spark ignition will be telling the coil to fire every compression stroke and exhaust stroke (wasted spark). Now the coils are designed in the 99+ application only fire on the compression stroke and thus have more time to re-energize before being fired again. In our cars with COP conversion the coils don't get as long to re-energize before discharging again which can lead to weak spark and spark blowout. Typically you can just tighten the plug gap and not worry but if you're shooting for big boost it may be a factor. [/QUOTE]
