Guys like I've posted before i went from a 3.42 GM gear to a 3.73 GM gear and of course my speedo is off. I have the programmer but as some of u know it dont have a 3.73 gear option. So could somone tell me wut RPM u ran at 50 or 60 MPH. Really and MPH wut RPM u ran so I can try to adjust the tire heigth on my programmer to get the speedo close as possible. I know it will still be 1-2 MPH off, but thats ok. Please somone holla back. THANX GUYS!

Use this equation for your most common speeds:
3.42/3.73 x 100 = 91.69% of your current speed.
50 mph would really be 45.85 mph
60mph is really 55.01 mph
As in my car, 60mph is really about 52 mph (going from 3.23 to 3.73)<b><a href=\"http://members.cox.net/95batmobile/d86f.jpg\" target=\"_blank\">Sinister Six©</b></a><br /><a href=\"http://www.sounddomain.com/id/95batmobile\" target=\"_blank\">My \'95 Bird</a><br />I am not afraid of storms, for I am learning how to sail my ship. -
