If you want launch control for wank factor then you are wasting your money and our time
It is a good way to break a lot of shit if you don't know what you are doing which it sounds like in your post
Do you do lots of track days/competition????
I DON'T have launch control on my rally car as so many things can change when you are at the start line grip levels wet/dry
You should be able to get off the line as good if not better without launch control
My 2 cents
