running 1J with NGK coppers (I just replaced them) I searched on SF and saw that there are 2 numbers people gap the spark plugs to and thats .24 and/or .28, currently I have mine gapped to .24.

Now everything runs smooth and such and the only issue I have is when I first start the car and start driving and the system is still in open loop/warming up and if the motor rev's to 3K rpm it'll break up a little bit but after it warms up it runs normal and theres zero break up, even under full boost/WOT.

NOW with that being said.... Is this cause for concern and should I regap them to .28? Or being that it doesn't have that issue after about 10-15 seconds of driving will it be ok?
