Later on I replaced the stock plugs with ZR-1 plugs and the wiring to MSD wiring, although I replaced my plugs before 3000 miles. After replacing the Max knock ret values are between 1.5 to 2 at WOT and constant Zero at cruising.
So check your plugs.

Will check the spark plugs tomorrow, i do remember when the extractors where getting put on he did mention something about the spark plugs. I was looking at changing the leads and plugs anyway. Who sells the zr1 spark plugs?
