I was kinda disappointed with my best time. You guys have any suggestions for pulling off better times, I was really nervous because it was my first time to the track so that might have something to do with it. I'm running a little bigger tires than normal as well. Got a K&N Cold Air Intake and Flowmaster 2 1/2" exhaust. Would new spark plugs and wires help me out? Kent 91+ White MTX
