2015 A8 C7 Stingray in for a ProCharger P1SC kit. This was the first Procharger kit we installed on a C7 Stingray. Very nice kit with no cutting of any part of your car. Intercooler is positioned very well at the front of the car for direct air flow. The car baselined at 389 RWHP. Final RWHP with the Procharger kit was 587/556.
