How much is my speedometer off?

I just installed my 3.73s from 3.23 and don't have a tune yet and was curious how much my speedometer is off. Anybody know how many mph the difference is?

Figured it out, it's just about 5 or so.

It will be off less when slower and more when faster. A GPS is nice to see where it's at or even a GPS phone app????

It's real easy to get accurate info for gear change or tire height using hp tuners and I imagine other tuning software is similar.
