More Audi RS4 Before & After Carbon Cleaning & ECU Upgrade Content!

[Kai@EliteMotorsports]

Customer dropped off their RS4 Monday morning for a CB service & an APR ECU upgrade. We decided to baseline the car on the dyno before touching anything. The car put down 281whp (lowest we've seen on this dyno yet). Upon removing the intake manifold it was obvious that this car had been worked on by another shop because they left a set of needle nose pliers under the intake manifold.

Anyway...At 33K miles this car def. had carbon buildup. After doing our cleaning process, we flashed the ECU with the APR software and back onto the dyno it went. With the cleaning and the ECU flash, this particular RS4 gained 25whp on the entire power band as well as a good bump in torque on 93 octane fuel.

Pictures below! If you're interested in this service let us know! Enjoy!
