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.

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

That's what I thought but I've never messed with it. Thanks for clearing that up

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.
