Grayson's 2013 GT-R checked in at AAM Competition with less than 8,000 miles. He already had a few bolt ons and we knew what to equip it with to complete the bolt on package. On stock turbos and 93 pump gas tune, Grayson's GT-R finished with a peak of 577 whp and 616 ft lbs of torque! Respectively over 650 crank hp! The driveability and instant spool of the stock turbos really makes these cars a blast to drive, now with all the bolt ons and a retune, they really do come to life!
