does the gap make a differece when dynoeing? I just put in some NGK 3330's gapped at .315 and wonder if the larger the gap the better the dyno and the smaller the gap the better the idle?

Yes the idle is rougher than with the stock plugs but not bad. It doesn't try to stall or anything. It sounds kinda rough like I may have something in store for the person next to me:rolleyes:
