hey guys just put some copper cores gapped to .060 in. everything feels right when driving, in fact it feels smooter but it sounds slightly rougher? to be honest it could have sounded the same but now i am noticing it. how do i know for sure im not getting misfires? i have a diablo tuner with toms tune loaded on it is there a data log i can run to know for sure?
