• HGP Turbonachrüstung readying 615+ horsepower Audi B9 RS4/RS5 EA839 2.9 V6 turbo upgrade

      HGP Turbonachrüstung (try saying that three times fast) in Germany is readying what looks to be a hybrid turbo upgrade for the EA839 2.9 liter twin turbo V6 powered Audi B9 RS4 and RS5. As far as AudiBoost knows tuners still do not have access to the ECU so it seems they will have the hardware ready before the software is fully mature.

      That is often the case these days but they are also claiming 615+ horsepower capability without any proof. Obviously the motor will be capable of that power but of course we want to see it.

      This upgrade should in theory carry over to other cars powered by this EA839 such as the Porsche Panamera 4S and the Cayenne S.

        so...rumor has it that the bosch ECU for the B58's have been cracked, its a similar DME to this B9 platform, so in a few months I think we will be seeing ECU tunes for this engine...much needed.
