Once again, the COBB Tuning AccessPORT proves to be the key to big-horsepower and unbelieveable performance as AMS Performance’s AccesPORT-Tuned GT-R tore off another amazing 1/4-mile pass. The AMS GT-R, powered with AMS’s big-turbo SR 850 Package and an AccessPORT broke the R35 GT-R 1/4-mile record with a 9.89-second pass at a blazing 145.98mph! This once again proves that these cars are best tuned on the factory ECU with the powerful COBB Tuning AccessPORT and AccessTUNER Pro software. We expect to see even lower ETs as the hunger for power and thirst for speed intensifies as the summer heats up!
