Is this the guy you are talking about? He’s *not* running this kit, and his car is not tuned. A stillen 370z with their tune sometimes makes no more than a full bolt-on 370z.

Fast Intentions went 12.4 then 11.4 with the same car. Like I said it’s all in the launch and controlling the power. They did this on only 8 lbs of boost on their turbo kit.
