Find the right launching point, which is right above halfway on the throttle meter, then after the car has finished launching, you can up that to around 75%. After shifting to second, let the car engage into second fully, then full throttle can be applied, and maybe a couple very fast clicks of nitrous. In 3rd Gear, full throttle can be applied but wait until the car has begun to accelerate again before pressing the nitrous to keep wheel spin from happening. From that point on just hold the nitrous and shift normally, you should pass the line almost at redline in 4th gear.
Thanks Kenny, and indeed it was the Perfect balance, although it did take a while to get it right.
