THALORD, are you making the power that brian is making. if you are, i would take it easy on that thing. the leaner you go, the hotter it is. i am pretty sure you know that. putting holes in the top of pistons comes from getting that cylinder too hot and the piston ring comes up higher than that cylinder and gas gets under the ring and when the spark plug ignites BOOM, there goes your piston. so if you are making the power brian is, i would take it easy, because those readings you are getting is very dangerous.
