Ran my 2015 GT-R at the GMP test n tune yesterday. 12 degrees celsius and sunny. Left tire pressures at street pressures (30 psi). 5000 kms on the odometer. Shifts felt a bit sluggish, so I think I need to get a optimization service done to calibrate the trans.
Did 3 runs, 2 were in the 10's, best was a 10.95 @ 122.66 mph. Only mods are a SBD non-resonated mid-pipe and SBD street spec cat-back, everything else is stock. Time-slip is attached. And yes, I know that my reaction time is terrible
