Ahhhh... I see
Thats pretty cool actually, I always thought external wastegates open suddenly, didn't know that it could open gradually.

So if I wanted to have the option of running 0psi for say up to 3000 rpm, would a boost controller allow me to leave the wastegate open to bleed off all the boost? Basically, can an electronic boost controller let you control how much boost you want whenever you want? Do I have the option of bleeding off as much boost as the wastegate can handle for most of the time. Then when I hit the track, I just press a button and I'm closing her up and running on max boost?

I understand that there are programs and chips to modify ecus to compensate for extra air. Then you've got to hit the dyno and tune the A/F. Are these programs capable of recognizing less air and therefore dumping less fuel? Am I stuck with I boost setting permanently with these ECU modifications?
