Last year I installed the Toyota 5 speed and the 4:08 Nissan diff along with a lower profile tire so my speedometer was off by about 12-15 MPH. This winter I sent it out to West Valley Auto Electronics in Resada CA for a rebuild and recalibration. There's a little exercise you have to go through before sending it out which determines how off it is. They rebuilt it, calibrated it, installed new odometer gears and replaced the cable guts in 10 days for $225. Today I hooker up my GPS unit which also shows MPH and went for a ride around town and on the highway. The speedo and the GPS were dead on up to about 50 MPH. Above 50, the speedo read about 3 mph higher than the GPS. That's pretty darn good in my book and the speedo is as smooth as it can be. Now I need to find a measured mile to test the odometer.
