When going down the track, you keep your foot floored the whole way (just like speed shifting). Then, when you hit the clutch to shift gears, the full throttle shift funciton activates a temporary rev limiter to prevent the car from overreving. Then, when you let off the clutch, that temporary rev limiter is shut off, and you can freely rev to your heart's content after that. So, basically it goes something like this... 1) set the full throttle shift to say 6500rpm 2) floor the gas, and go down the track 3) hit the clutch while keeping the gas floored and it will bounce off the 6500rpm as you shift into the next gear 4) let off the clutch and you can rev as high as you want again. This is a nice safety feature if you're not that great of a speed shifter. What can happen is if you miss the shift, and then your revs head up to the redzone and bounces off the factory/JWT rev limiter (not good for your engine). This keeps your turbos spooled and revs up... because you don't let off the gas. In fact, it may theoretically keep the turbos even more spooled than normal speed shifting because when it hits the rev limiter, there's load on the engine (thus more exhaust power and in turn boost).
