Well, new plugs didn't help me out so much. Still getting around 11-12, although the enhanced throttle response is great! I'm getting some AMSOIL 5w-30 in a couple days, hopefully it smooths out the engine. But I'm really looking towards the o2 sensor. If you look at my video on the 3rd gen exhaust thread, you'll notice that at 4k(park redline) there is a big puff of black smoke that comes out.
