I pulled my plugs today.. The bottoms were black thanks to my rich settings, but the electrodes are turning white.. I guess i am running hot, i am using ngk bkr7e's gapped at .28 with the ignintion timing retarded a bit.. I dont think i have any vaccum leaks anywhere... Anyone have any tips to help me or is this actually normal for a boosted b18b making about 230whp? thanks

I used fuel grade hose from Advanced Auto. Haven't had any problems with it yet.
