In a recent comparison test conducted by AWE-Tuning in Willow Grove, Pennsylvania, the GIAC performance
calibration for the 2011 Panamera ® Turbo made a 75% greater horsepower gain over stock than one of the
more aggressively marketed piggybacks.
Piggybacks can introduce many issues into an engine control system. Using a resistor to alter the signal
coming from the boost sensor to the computer on a Panamera ® Turbo will not just trick the computer into
thinking the system is making less boost. This inaccurate signal will affect the computer on a whole host
of other parameters including boost ramp up, fuel, timing, and knock correction as well as many other
motor and turbo related safety responses.
A proper ECU calibration will always allow the computer to receive more accurate information and make
better decisions. This test was about power however, and the GIAC calibration comes out on top with its
91WHP / 50WTQ over stock, and 39WHP / 19WTQ over the piggyback module.
