Welcome aboard. Ditch the iridium waste-of-time plugs in favor of regular old NGKs. You'll get no gains from the fancy plugs without a lot of motor work. Also, running 91 octane is a waste of money, as you do not need it. PROTIP: Higher octane ratings actually mean the gas is less explosive, which comes in handy when boosted or higher compression. Otherwise, you're probably going to lose power by running 91 in a stock 2GNT.
Lots of good info here. Looking forward to the pics.
