So took delivery of my brand new 2020 S6 weeks ago, and as soon as I got it I installed a JB4 ¸(same module as the RS5)

first pull on map 3, the car felt like a total different car, 21psi vs 14psi you can really see the difference in the driver seat, HOWEVER,

seems like the transmission cant take that much power without poppin a tranny code and CEL,

so I erased the code and did map 1 and 2, they both did the same thing, after 200kmh the tranny code pops and the cel too, code was P2CD5 (read the code with an innova obd2 scanner, was all i had at this moment)


Talked to george at Burger motorsports but seems likes theres not much to do, we are trying things but seems like im one of the first S6 tuned with JB4

So was wondering anyone else as tuned their C8?

Encountered any problems?

Is there a transmission tuned available? Sure this will solve my problems!
