First off is a beautiful 335is that drove down from Charleston, SC. Car already had a off the shelf 'Race' tune on it (run 2). We dyno tuned it from there. This car has Stock Turbos and Stock Inlets and was running on an E85 mix and meth.
Next We tuned a E92 M3 after adding test pipes. First run is stock tune, 2nd run is our off the shelf tune and the last run is after dyno tuning on top of that.
