The Q50 I drove as a loaner car had two sport modes. The obvious one and one hidden in the menus on the display screens. Turn the sport mode on in both places and the car woke up like crazy.
That being said my 07 G35 Sedan 3.5HR still felt quicker. On the factory tuning before any updates the throttle response was almost too aggressive. The update flash that Uprev based their tuning on was lame by comparison.
Tuned/Moded I can stomp the 07 at 60 mph and still haze the tires.
Uprev tuned by me with their throttle map, K&Ns, HPS intake tubes, Stillen underdrive pulley, DC Sport headers, Z1 highflow cats and a custom 2.5" exhaust with a X-pipe, 2 magnaflow 4" case 18" long magnapack mufflers in place of the resonators and 2 magnaflow 14" case offset inlet/center outlet mufflers in place of the rear mufflers.
