Practice makes perfect. If you don't want no one to see your times at the track let them know and it won't display it on the tree to the public. Just keep practicing. I couldn't give you advice on how I launch cuz a boosted car will launch diffrent but try dropping the hammer at about 3-4k.....then try feathering the clutch see what works better. Feathering will kill you clutch faster though so its up to you.
