I believe you need the ECU recalibrated because the Roush cluster goes beyond our stock 120mph. I know that is what happens when you reface your cluster to a Saleen where it shows 160. Curious to know about this too. Good question
just out of curiosity but why does your gauge only have 2 things in the middle? and that funky reset button in the middle? and shouldn't the GT gauge go up to 140?
The cheap way out would be to get a new gauge face. Not sure if they make them, but there are many places that make custom faces. Look around. If you don't care about the MPH going that high, then i would go that route. Much cheaper, no computer tune needed.

yea if the speedo and tach show the same amount then it wont need to be recalibrated but who knows since it doesnt sound like anyone has done a full cluster swap.
