GIAC software for the Porsche Macan S is now available! This is a true ECU upgrade for the Porsche Macan, as opposed to a piggy-back upgrade (using false signals to control ECU outputs).
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:
- 35 wheel horsepower and 110 wheel torque on 91 octane
*Higher power gains will be realized on 93 octane
Hardware requirements:
Other benefits to GIAC software include:
- Improved throttle response
- Improved fuel economy
- Removed speed limiter
*Currently, ECU's must be flashed at GIAC's facilities in Irvine, CA. As such, out-of-state customers are welcomed to contact us to arrange shipping and payment, and we will ensure a 1-2 day ECU turnaround. In addition, customers outside of California are not subject to sales tax.
