So I have had my stang for a couple weeks now and up till this morning on my way home from work i had only had it to 120.. I couldnt take it i had to see what she really had and WOW!!! Maxed out the speedo at the stopper past 150 and was still gaining good speed, This was very dumb considering i was on a back road with tons of bumps and bridges, Still not sure what all is done to the car yet so far i know its got a bullitt engine, pro 50 shifter off road x pipe to the mufflers(no cats) an sct chip and possibly gears..
