Porsche Panamera Turbo (S) 2010+ GIAC Performance ECU Software Upgrade

GIAC 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 software gives you power gains of: - 58 wheel horsepower and 51 wheel torque on 91 octane - Estimated crankshaft power output of 570 horsepower and 578 lb. ft. of torque Hardware requirements: - IPD plenum (recommended) Other benefits to GIAC software include: - Improved throttle response - Improved fuel economy - Removed speed limiter *2010+ model year Panamera Turbo ECU's must be flashed at GIAC's facilities in Irvine, CA.
