Tip in is usually the application of throttle from at rest (Not pushing the pedal at all) to just a little application of the pedal (regular driving when pulling out). Basically when you get a tune on your car, that is one of the things a "good" tuner will do. It just "feels" better when pulling out normally.
Not sure if that is what they're calling it though.
