So I originally had a steel driveshaft and what I believe were 2.73s. I swapped rears not too long ago. The seller said it had 3.23s. I took it to TTP & had Matt recalibrate the speedo for 3.23s, however, the speedo is still off. So what gears could it be & how can I find out?

Speedo will show 40, Nav will show 45
Speedo will show 65, Nav will be showing 80.

I had a police officer use his radar gun to check my speed for me, and sure enough I was going faster than the speedometer showed.

So, what gear options are out there for these rears, and what gears could it be?
