Breaking up under WOT and spark plugs?

[Sleeper4SHO]

I have a 2011 SHO PP with Torrie boost tune 93 oct/K&N CAI/Borla catback. Car has been great since Nov when i purchased it and installed the tune/cai/exhaust. Lately it's been breaking up under WOT pulls and the check engine light flashes for about a minute then goes off. Car runs fine under normal driving conditions. Initial thought is to replace the spark plugs. What plugs is everyone running? what gap? Torrie recommended the NGK plugs he offers on his site but just curios what everyone else has going on. Also, does anyone think changing the plugs will fix my issue?

Thanks in advance to all.

I use Motorcraft SP534's. But more importantly, they are gapped at 30. Changing to new plugs and gapping properly may solve your problem.

Installed new NGK plugs from Torrie. Car runs great! Time to do some data logging and get the new tune so I can install 170 tstat and 3 bar map
