BMS is working on a JB4 setup and should have it out soon, VR tuning and Racechip are a couple of other proven options. I ran a Chipwerke piggyback on my 2013 S4 for the better part of 4 years with zero issues, it took 1/2 second off my 1/4 ET and added 4+mph of trap speed. I just purchased a used Racechip from another forum member (who sold his car) for my new S6. I've only got 600 miles on my car so I have been really easy but rolling into the gas with the tuner on the factory default setting makes the car pull way harder, especially in the higher rpm where it seemed to flatten out. I plan to purchase the JB4 once it's released....... was really planning to go with Unitronic or EPL for flash from home options but after reading the PODS warranty thread where a number of people got TD1'd after flashing back to stock scared me away from that idea. This is one of my DD cars and I'm not interested in blowing my warranty....... I have my Z06 for that.
Jb4 sounds like a good idea to save warranty but how does it compare to APR Stage 2 with DPs? Initially the car felt pretty quick but now not so much. If I cant figure a way to go Stage 2 through this Audi dealer and keep my warranty I may try the JB4 if it's not detectable.
My other option is leave the S6 alone and pick up a R1 to use from like April till October ish
