[]That's not good! For the speedo thing, i have 245/50/16s and when we bought the car the guy that owned itsaid he was pulled over by a copon the interstate for going 10 over so he told us the speedo was off by 10....interesting coincidence.

I've tried everything from pacing another car at a known speed. Timing mile markers. Peering into another car that has a digital dash but it all still does not account for error in the other vehicle.

My latest speedometer checks have been against GPS.



Even the same car with new vs old tires can vary the speed by about 5km/hr.

well i started from 287 in jersey up all the way to vermont. i got pulled over in moreau in saratoga county i was almost at exit 20 when i got pulled over really sucked. i wasnt sure if i had my lisence back or not so i was getting ready to call my dad and tell him he needed to drive 3 hours to come bail me out of jail but i had it back talk about freaking out

That sucks.
I work off exit 9 and I live by the thruway (90).

i have 3.08s, at 45 in 5th im fine, comfortable.... and 2500=85mph for me

HACKGT350

i had to pass that exit i start about 15 minutes before the tolls then i hit the tolls and the exits start over again. haha on my way home i stalled out at a toll and my car wouldnt start i looked like a dumb *** running with my car and jump starting it

yeah not me i didnt even come close to hitting 2500 rpm at all would have put me up over 100mph and there is no way i can put it in 5th at 45 the car just doesnt want to move could be because im carburated and your efi

sounds like you have 2.73's then

HACKGT350

would the vin tell what gears i have in the rear? i also have the build sheet that should say as well but from what i have been told my car came with 3.08's all the 20th anniversary 5.0 hatches came with 3.08's for some reason unless someone swapped my rear for another 7.5 which i wouldnt be surprised
