It can han happen at any throttle postion as long as rev\'s can build and boost can build.
Shot this video last night on way home. Unfortunatley it doesn\'t do it as bad as it has been in the link.
I stayed in 4th gear after driving at 50-60km\'s (I did this on a quiet 100km/h zone road to play it safe ) All i did is gave it some gas, Dont think it was WOT, and let the boost and rev\'s build up to get to speed. After it made its fun with the rev\'s it build like normal, and will keep accelerating fine
And to top my bad luck off, after I stopped recoding, A car over took and flicked stones everywhere, Cracking my windscreen and Drivers side spotlight, So Does anyone know where to get one from to replace it??? :\'( It hasn\'t been my week.
