clued up on it and how does it work
Launch control makes boost when the engine is revving off load, with the car stationary before a launch.
Anti lag makes boost when ever your car is off boost or off throttle, so with the car moving with a closed throttle you will still have boost, ready for you to jump back on the throttle with little/zero lag.
For all my bitching, mine will have launch control which sounds similar, so basically cool a fuck lol
But anti-lag as every one has said in the past (except for Jano) will just destroy your turbo, and you really can't use it on the road... the track is another story though
