are these the right settings for my speedo I have a rearend from a 2001 camaro SS with 4.10's in my 95z28 and I am off 7-8MPH my computers is reading 75 in datamaster and my car is at 83

 

If you selected Tools-Speedometer Calibration on the Tuner tool bar and then enter tire size OR tire revolutions per mile, then enter rear gearing and aslo make sure F-Body radial button is selected the info should all be calibrated and inputted in the constants fields for you. W/O your tire size I can't verify your settings. For a more accurate setting go to TIRERACK web site find your tires, click on specifications tab, and find the revolutions per mile, it's more accurate than using a generic tire size.

 

Bump I have all stock tires

 

The settings are correct for a '94-95, F-Body, Automatic, w/245-50/16 tires and 4.10:1 rear.
