Looking very nice and fast. turbo ftw
But i think your clutch is a bit slipping without you notice it. You pull in 3rth till 135km/h and you can easely go to 145km/h, I had that aswell, changed the clutch and i had in all gears arround +10 and some even +15km/h speed more!!!!!!!!
OR you don't pull to 7000rpm
