I wait until both staging lights light up and then get on it. I find that if I start any earlier I will kick my meth on and its all or nothing so major bogging. If I wait until I see the first yellow on the tree to light its already to late. Good luck with it. What is your 2 step set at?

Data logs would definetly help.

 

Thats because your not using the launch maps to get boost built in a sec or 2. When the first yellow starts going down the tree I start revving up slowly then i'm full throttle by the third yellow....
