Macan 2.9L ECU upgrade is now available

The GIAC Stage 1+ Macan 2.9L ECU upgrade is now available for all Macan 2.9 liter Twin-Turbo Platforms.

We are proud to present the GIAC Stage 1+ ECU tune for the 2019 - 2021 Macan GTS, 2019 - 2021 Macan Turbo, 2022 Macan S, and 2022 Macan GTS. The GIAC stage 1 plus program offers smooth part throttle driving while boosting full throttle power gains throughout the rev range. The calibration includes increased boost, changes in fueling and timing, as well as higher torque limits to yield peak power.

The engine horsepower and torque graphs are estimated from wheel dyno tests. GIAC tuning does not change the knock sensor thresholds from their original OEM levels for the optimum balance of performance and component longevity.

The installation process is completed over the OBDII port using GIAC's proprietary programming suite and flashing cable. All programs include a full recalibration of part and full throttle driving characteristics, offering massive improvements to acceleration and overall responsiveness.
