Info
GIAC Stage 1 Plus adds horsepower, torque and more throttle response throughout the power band. This calibration is compatible with vehicles that have no other upgrades to basic "bolt-ons".
While testing this platform, we noted significant differences in performance potential between 91 and 93 octane. The GIAC stage 1 program is designed to make the most of either fuel and will perform significantly better on 93 octane. At this time the 2021 model year with ECU part number 8W0907559S is OBD fashable, while earlier 2018 - 2020 models must be sent in to GIAC for bench flash.
