Toyota Spedo calibration

[dark knight]

There was information I had read a long time back about different speedo gears that would calibrate for R&P/Tire changes on a Toyota pickup. It is a small gear that is in the Tcase which the speedo cable connects to. I can't find shit for information on this any longer. Do any of y'all know about the speedo gears or have info on correct one to match speedo with 5.29 R&P with 35" tires?

Refer to thread below. I got a module from commercial speedo in Sacramento. It’s dead nuts at 60mph now.

5.29s and 35s should be back about the stock ratios. Use a GPS app like Waze to see how far off it really is.

Lol, GPS is why I got the speedo module, I didn’t just go at this blind. The speedo was reading about 8mph higher than actual speed. I’m running the above gear/tire with an R150f.
