    First off, I know we have to scan, scan, scan, but I dont have that capability right now. My best time at the track is 14.2's since the new tune. Mods are....3.4 pulley, ported blower case, heat shield, headers, 3 inch full exhaust, "im an idiot" and bought the alt. rewire kit, MSP CAI w/Spectre filter, AL103's, 8mm wires, headers are wrapped, no converter, poly mounts, new trans and engine mount, oversized tensioner pulley, 3800series.com tune and case relearn, 93 ocatane only, havent had it scaned since the placement of the tune. Should I move up, or down a pulley, or should I let sleeping dogs ya know....sleep, until I move up in the world of modifications. Obviously i have to ahve it scaned, I know. Thoughts please.

    Scan and see, you will need a custom tune to go smaller.
