I don't have a GPS but I used a Tremec gear calc and heres what's odd:
Speedo and RPM read ~74-75mph and ~3150ish rpm which is clearly wrong as im traveling 70mph.
From tremec's website the car should spin 2960rpm at 70 and sure enough with no offset, the scan gauge read 70mph @ 2960rpm. So goofy gauges, but the obd2 signal to the scan gauge is 100% correct.
