R35 GT-R Alpha 6 Performance Upgrade Package


SKU: ALP.07.10.0001-1

The Alpha 6 GT-R could pass for a stock vehicle under cruising conditions because of the proper re-calibration of the ECU. When you lay on the throttle, the differences become very clear as the speedometer needle wraps around in a hurry!  We have seen a best drag time of 10.6 @ 130 mph on 93 octane pump gas with this race-proven package.



At the heart of the Alpha 6 package is our tried-and-true tuning map. Through rigorous testing, we have developed a file for your car’s computer that extracts the most safe and reliable horsepower possible. In addition to the computer recalibration, we utilize HKS air filters to allow the turbos to breathe easier – allowing maximum efficiency of the factory intake system. Finally, we include a complete AMS spec exhaust system that adds even more horsepower along with a throaty tone to convey the appropriate bark to your GT-R’s bite!

The key to the success of the Alpha 6 is freeing up exhaust flow with a properly tuned downpipe design. In addition, we improve the cam timing characteristics while increasing turbo output. In doing so, we are able to make impressive power gains of 120HP! You will certainly notice improved response due to quicker turbo spool; the system yielding a significantly wider power band than stock.
