Speedometer Correction After 3:73 Gears

[squares98]

i got the gear in mine ... been there for like 6 months now ... its still 5 mph off ..i dont think there is a 100% fix for this ..

I have the same results as you with the 23t gear, 5mph off..

I thought the speedcal was pretty good to go as far as being accurate (see my above post) - especially when compared to the plastic gear change. Mabye someone who has one can chime in here?

yup, speedcal is by far the most accurate way to correct the speedo other than a tune. but many handheld tuners don't go farther back than '98.
