APR C7.5 S6 / S7 ECU & TCU Upgrade: Now Available at RSW


More Horsepower IS HERE for the C7 and C7.5 S6/S7 Owner

APR coming through again with some more goodness for the 4.0T platform. As if two turbos and 8 cylinders wasn’t enough to begin with, they have managed to squeeze out approximately 574 hp and 638 ft lbs. of torque. That’s gains of 165hp and 209 ft lbs. peak on 93 Octane with just a Stage 1 ECU Upgrade!

We wonder what one of these S6 / S7 would be like at Stage 2, or perhaps even Stage 3 with RS7 Turbocharger Upgrade?

If you have any questions or interest in getting your 4.0T reflashed with the latest software please let us know. Existing APR customers pay nothing for the update, new customers the upgrade is the same pricing you will see directly at APR.

In addition to the ECU update, APR has released the DL501 S-tronic TCU Upgrade as well for the S6.
