Speedometer calibration

Speedometer calibration
I recently bought a 2007 GT that had some mods. These mods where removed to pass emission testing. The CPU was reset to Ford specs, however I notice the speedometer is off by 10mph. I have heard of an engineer mode that might calibrate the speedometer, anyone know how to access this mode? Also the heater works great, but in defrost mode no air comes through the vents toward windshield.
