Here i have a RaceChip Ultimate which i had in the car for only 5 months before i decided to trade-up my Audi. This chip definitely made a difference in the performance of my 2016 S4. It\'s relatively easy to install and remove if you need warranty work done it taps into just two sensors on top of the supercharger. The Boost Sensor and Fuel pressure Sensor. You will need to make sure that you align the connector clips in the correct direction and that it clips into the receiving connector\'s tab. The board has 9 settings so you can easily increase the power delivery depending on how responsive or aggressive you want the car to respond. I always left it in setting 7 and that was plenty for me! - This is equivalent to a Stage 1 map as it increases power from 333hp to 395hp (As advertised) and gives a nice 70nm of torque increase (as advertised). It will work with the latest 2015/2016 3.0 V6 Supercharged 333hp(245kw) engine with 3 pins (SENT) Sensors found in the S4/S5/Q7 and A6 C7. this unit retails for $899 US dollars, it has no scratches and is in pretty much new condition, so my loss is your gain!. This chip had just been taken out of the car and i can guarantee that it works!!..it\'s fully operational so i will take no returns .

Please Check the pictures before you buy and make sure your engine has 3 pin sensors CREC or Similar type Audi engine with 3 pinnot 4 pin

I posted the picture of the correct engine and the one that\'s not compatible.
