GIAC Stage 1 & Stage 2 software calibrations are now available for Audi S1 models. Stage 1 software is designed to accommodate the factory exhaust and intake systems. The programming retains OEM-like drivability while maximizing performance improvements throughout the power band. On 98 RON fuel, peak-to-peak performance gains have been measured at 30-35 wheel HP and 15-20 ft lbs wheel torque. Stage 2 software is optimized for an upgraded intake, intercooler, turbo-back exhaust and MK7 GTI Turbo outlet elbow (required for maximized power gains). Special thanks to E&A Autosport in Israel for assisting us in the testing process by providing several development vehicles!
Other features of GIAC S1 performance software include:
- properly recalibrated air/fuel ratios to reduce cylinder pressure at higher boost pressure
- improved throttle response for a drive-by-cable system feel
- OBD2 installation allows for quick, reliable and easy performance software installation
- raised speed limiters to factory redline in final drive gear
