The speedometer is off 4mph. It was 8mph and they put a new instrument cluster in it and it made it only 4mph.

Any ideas?

And this has a pro charger super charger on it.

It was all bolt on.

The only chip that was installed was a ford racing package and it looks like someone tuned the MAF sensor.
