well i know its a different car..but anyways for comparison..

my stock gap is .044

gap on boost is .022

Generally nobody goes smaller than .028 on anything resembling a street car. Really no gains smaller than that. We normally run NGK coppers at .030-.035.

well i had a misfire issue..and gapping down to .022 was the only option...i had done negated all the fuel i could...gapping that low fixed the miss up top. i got a graph to show the miss..originally i had figured it was a maf issue..however untrue...it was a spark issue.

i have never decreased gap size, do you just press down on the top of the plug??"

yeah just be careful not to tap it shut

not enough fuel, too much fuel, maf, spark blowout...damaged internals and rings..ect.
