What boost is it putting out?
What was your 60' time?
What gas were you running? (all gas is bad now btw...)
Not a BAD time, but something seems a little off. Not to dis on you, but maybe we find it and knock off 2 or 3 tenths. I have ran one OEM to a 15.6... so chipped even w/ audio should walk it I'd think. 200 extra pounds versus a chip adding minimum 20 WHP and 40 WTQ is over come easily.
