Sorry to hear about your women guys. I've been blessed with a good wife, and I'm mighty grateful. She's as much of a Mustang nut as I am.
My '05 GT auto 'vert with a CAI, 89 octane tune, underdrives and aluminum driveshaft turns between 5 and 5.1 s with no attempt at a good launch. Out on the bypass highway (speed limit 55) when the light turns green, floor it even with TC on. OK, so 60 is a little illegal, but not much. Maybe I could do a little better with a more aggresive launch technique, but I'm not a racer and I don't want to burn off too much of those expensive Pirellis.
