K&N panel filter, Tomei EL, Tomei OP, OEM FP, Thermal R&D catback. I think I will keep the default tune loaded even though my AFR @6800 rpm @WOT is above 11.9. I ran the rich 2% of v146 for over a year and my exhaust got very sooty, would pop and backfire on decel, and had anemic throttle response at low revs. I recently changed spark plugs and found the tips were very sooty as well.
