Description

+164 PS, +344 Nm

The dyno graph is from a car with a milltek catback exhaust, expect 720 PS on a completely stock car.

Before tuning any of these cars, they have a set of problems that must be checked:

  1. The stock intercoolers develop hundreds of pinhole sized holes - essentially like swiss cheese. Pressure test the intake (you can do that from the bottom of the car, take the intercooler hoses off, blank one, pressure test from the other, it should hold pressure). If the intercoolers don't hold pressure, replace the intercoolers.
  2. The wastegate actuators on the turbos become loose over time and the car barely even makes stock boost. Log the wastegate duty cycle on the car, if it is 90% or over at high RPM on the stock tune, then the actuators are damaged. In this case there is no shortcut - the turbochargers must be renewed.

SAI, CAT and Rear O2 diagnosis is disabled in this tune. 98 RON.

TCU tune is required, see here: Audi_RS6_4F_5.0T_4F5910156P_0020_ZC1C08_DI06
