    12.7s

    took the truck to the truck now on drag radials and ran 12.7s on funny gas, but its slugging on the top in on motor, plus check engine light is still on."mass air flow sensor problems. so i know it should be running a lot better.

    You're telling me you run 14 flat or better on motor with nothing but exhaust and a stall?
