The benefit to this is bringing the car into the powerband much quicker, making it feel much peppier and "ready-to-go"
It's pretty nice on a lot of road courses because it will let you spend more time in 3rd gear without needing a downshift to 2nd.
I think there is a lot of information available if you google it, but I'm happy to answer any specific questions you have on it.
