Speedometer calibration
#5
I had my PCM flashed with my correct info (37" tires and 4.88 gears) and my speedometer is now within reason. Not perfect, but close enough.
I don't know if it's worth the cost to have it done just for that but I needed it done anyway, so why not correct the speedo in the process.

Tom, how far were you off, with that tire and gear combo?
From the calculators online, if I regear to 4.30s, the speedo will be Almsot exactly back on, with my 33s. Unfortunately I can't find a set of 4.30 gears for the front, so I'll be going with 4.56s eventually. Looks like it'll put the speedo fairly close

If you go with 4.56s, you have an excuse to upgrade to 35s in the future, right? ;-)

Don't know how long the front diff could hold up to 35s lol!

You just buy your own programmer or just take it to a place?
