Data, in our engines is everything in siquence and there is no one particular thing which can be modded to increase power. We just have to make sure ( when we do modding) everything is right and on time.
About the carb modding-it will not add a lot of top end power ( we are talking about carbs which initialy done well-Novas, Sirios etc), but we can inrease respond, we can encrease efficiencyduring the accelaration, decrease unneccesary fuel loss on not wide open moments etc.
About the timing altering you saw-it is unique today, I hope you got point what I did there. I am sure very soon someone will copy it and I am OK with that.
Will be at CP this Saturday, we can talk more.
