For the third part of our conversation with Harvey Epstein from The Boostcreep, we went in depth as to what it actually means to "Tune" a car?

If you have had your car tuned, most likely you have seen a Tuner/Calibrator like Harvey sit in your car with a laptop making changes, but what exactly are they doing?

Harvey was gracious enough to give us some good insight into what his process is for developing a tune on a car, and some of what his process is and what he is looking for.

Hopefully this helps to remove some of the mystery about what happens through the process of changing the calibration of your ECU.
