Porsche Cayenne Turbo (S) 2011+ GIAC Performance ECU Software Upgrade Add Overnight Return Shipping::No We recommend that the ECUGIAC is the only software manufacturer that provides a true ECU upgrade for the Panamera Turbo. Other manufacturers offer either a piggy back upgrade (using false signals to control ECU outputs), or flash OEM "S" files. This is evident by the fact that the factory speed limiter still remains active. With a piggy back upgrade, you will typically miss out on an extra 30 40 wheel horsepower when compared to a true software flash. GIAC performance
