I just got done tuning (with HPTuners) a 2007 Mustang GT with the 5 speed that had a Procharger and 4.10 rear gears. Everything I did to account for the gears had no effect. The speedo is still way off. Any ideas?
Thanks,
Don

It's kind of funny you mention this... I just noticed that the PCM thinks I have 3.31 gears, but according to the stamping on my rear housing I have 3.55's (which is what I ordered the car with), and yet according to a cop buddy of mine's radar gun, my speedo is dead on...
