well i am not sure if it was a 911 or not because he turned before i could see the front. i think it was though because boxters look a little different. my spedo is off by 3 mph. i have gon over 155 mph before the previous owner(i think) took it off. but when taylor gets the 911 broke in then we can go. but i am putting nos on my car. i will be at test and tune thursday night so if its broke in by then we can go. i was pissed bout my time so im gonna spray. its only a 50 shot though.
