Alex, I have to say your run figures are rather interesting... You have the advantage of the PDK and launch control that gives you a better 0-100 than mine. In my case, my car continues to burn rubber till mid range of 2nd gear...
On the other hand, the PDK as far as I know doesn't provide the same horsepower as the manual... in terms of numbers yours produce less HP yet it's faster in acceleration than MT.
You can switch to Hi Boost on the Greddy to reach your desired 0.4 bar. But it's advised to use racing fuel for it.
I guess the bottom line isn't how many horsepowers can you reach, or how much boost can you run rather than how much of that can your car put to the ground.
Forget the numbers and go unleash your beast to mark its territory
