So, the APR ECU tune also includes new TCU programming-----From APR's Website:
"The APR RS6 ECU Upgrade also includes new programming for the transmission computer in the car, raising the shift points by 200rpm."
I assume by the sentiment on the baord, the preference is the MTM TCU upgrade... Can someone explain the additional differences/attributes (beyond the raised 200rpm shift points) of the MTM vs. APR TCU upgrade?
Thanks!
