Similar to a post above, I have a 1997 S-10, 4.3 auto that I put a 3.73 rear end now and the speedometer is way high.

How do I fix this? With a programmer or a module from a manual S-10?

Any help would be appreciated.

Thanks,

Chris

Speedo calibration

A hypertech PP3 will allow you to recalibrate your speedo according to the gears you have and your tire size as well, if not stock. And the added bonus of bumping up Speed limiter, rev limiter, and tweaking your shift points! Easiest way. Not the cheapest though.
