TuneZilla Performance TCU Tune - VW / Mk4 / Golf / Jetta / New Beetle / 1.9L BEW TDI

This is an automatic transmission tune (DSG type) that increases the torque limiter and in some cases lowers the RPM shift points to help you stay in the best efficiency or torque range.

This is not required for all PDs tunes, even Stage 4. If you get this transmission tune, then you may experience slightly smoother shifts.
