GIAC Stage 2 software upgrades are now available for the MK7 Golf R and 8V Audi S3!
GIAC Stage 2 software upgrades are now available for the MK7 Golf R and 8V Audi S3. Designed for upgraded turbo back exhaust, intercooler and cold air intake, this program offers dramatic performance improvements over factory software, while retaining factory-like drivability. On 91 octane fuel, performance gains were 70-85* wheel horsepower and 75-85* ft. /lbs. of torque. In certain areas of the power band, gains reached as high as 89 all wheel horsepower and 81 ft. /lbs. of torque (91 octane fuel). As with our stage 1 calibration, our software features a proprietary boost control system to optimize air flow and horsepower. Our engineers have developed this calibration to ensure smooth drive quality and no issues with surging, turbo over speed, EPC lights or limp modes. For DSG models, we've spent a great deal of time combating power loss across shifts, specifically the 1-2 (from a launch control) and 4-5 gear shifts. One item to note: This Stage 2 calibration is not compatible with ethanol blending, as the factory fuel system cannot support it at this power level. Use of any sort of ethanol fuel blend (beyond what is found in normal 91 or 93 octane fuel) will cause fuel starvation limp mode issues.
Features for this new revision are:
- Increased linearity with low speed power control and accelerator input -
New version spreads power more evenly across throttle input allowing for absolute driver input. Throttle response is still improved for a drive-by-cable system feel.
- More continuous power under the curve -
Smoothed low end torque spike and increased torque and hp under the entire power curve.
- More precise boost control across gears -
New revision utilizes a vastly superior proprietary system for boost control with added over boost protection, allowing for consistent boost levels across all gears and in all conditions.
- Properly calibrated air/fuel ratios for specific fuel types -
Low emissions vehicle run lean Air / Fuel ratios to meet strict emissions standards which are safe, but not optimal for increase performance. GIAC engineers optimize Air / Fuel ratios for the increase power levels generated by GIAC performance software.
- Raised speed limiters to factory redline in final drive gear -
Top speed of vehicle raised to the redline in the overdrive gear, or at the point of maximum aerodynamic drag (whichever comes first).
- Optimized torque control for smoother, faster shifting with consistent power across all gears -
Factory torque requests are set for factory power levels, GIAC torque optimization adjusts ECU settings to function properly with increased torque/horsepower levels.
- $150.00 upgrade for existing GIAC Stage 1 users, $750.00 MSRP* for new users -
*MSRP pricing for U.S. / Canada. International customers contact your local GIAC distributor for local MSRP pricing.
GIACís Flashloader handheld switcher is available for this application, allowing the user to switch between pump and race gas modes.
