Speedometer adjustment

Running stock rims and tires, my Speedometer is showing 55mph, but GPS shows 58. I setup the Edge CTS to do corrected MPH with stock numbers (so basically no correction) and it reports the accurate same as the GPS. How to I fix the needle to show the correct speed?

My speedo is the same way, expect mines 3 mph fast.... I left it cause it helps me with speeding tickets. Here's a bump for you.

You can use an SCT tuner to adjust tire revs per mile. Corrects speedometer and sets shift points optimally.

I thought it only corrected shift timing... Good to know!

The SCT only does shifting. You need an auto enginunity to adjust speedo issues

So it looks like I don't have what's needed. Oh well, I know I can run a half a mark fast and be safe. I'll just have to deal with it. Thanks.
