Oh hi there. Today, we discuss Transmission Control Unit tunes, and what their purpose is. Do they affect everyday drivability? Do they help performance? And what do they mean for the longevity of your transmission? We test out Unitronic's Stage 2 DSG TCU Tune, on this C7.5 Audi S6, with a couple arbitrary 0-60 tests, and driveability tests! Next up, 1/4 mile tests.

This is the TCU tune from unitronic: https://www.getunitronic.com/tcu-tuni...
