The 2011 GTR has a mid pipe and Cobb tune (550 at flywheel). My cobra has a whipple 18 lbs boost (600 rwp 520 rwt). On a closed course, I was in 3rd gear at 3k rpms and I let the GTR get the jump. He instantly put 1 cars on me before I floored it as I didn't think his car was that fast, huge mistake. I hit 4th gear and he was 1.5 cars ahead, by the end of 4th he was 2.5 cars ahead. Just before I let off the gas I looked at the speedo at the top of 5th gear which read 150 mph and he was likely 3-4 cars ahead of me. I was really impressed at the GTR with minimal mods. I was wondering if anyone else has had any run ins with any GTR and if so what are your mods and what was outcome? What can I do to my car to up power, my mods are 2.3 whipple 18lbs boost, airfuel 11.5, timming 19*,next gen JLT with filter in fender,cat back, cat less x-pipe, lethal budget return fuel system. I appreciate any help.
