    • B9 Audi RS5 with ECU flash tune only EA839 2.9 V6 runs 11.5@121.6 1/4 mile

      Now, an 11.5 @ 121.6 in the 1/4 mile is not slow. It is closer to what you would want the brand new RS5 to do out of the box though. Considering BMW has SUV's that can run 10's tune only now Audi is dropping the performance ball somewhat with the RS4 and RS5.


      It is odd considering what a beast the RS3 and TT-RS 2.5 TFSI's are. The EA839 V6 in both 3.0 single and 2.9 twin turbo form seems to be a letdown.

      This RS5 is tuned by Etuners Australia and on the conservative Dyno Dynamics picks up around 50 awhp:


      Now that is an extremely conservative dynamometer but this thing is not making big power stock. Even modified the numbers are somewhat disappointing.

      The RS5 and RS4 are going to need upgraded turbos it looks like to even play with what the next generation or current generation from BMW and Mercedes are doing on factory turbos:

        True but this isn't running 10's with some ethanol splashed in.

        top-end power is there, it's gaining 28mph in the back half, so I wonder what's holding it back in the 1st half?
