yea.....kinda
Yes, the electronic boost controllers do keep the gate shut more, but not all the way.
The solenoid still lets the wastegate door open a little and then tries to compensate to the correct boost level set, buy letting more or less air to the wastegate valve.
It is pretty fast, but the solenoid is like a fuel injector. The controller pulses the 12volts on and off to get the correct amount of air to open or close the wastegate. This leaves some room for improvement since most wastegates are slow to react. This is why there is more spike with them. They can't keep up.
It's still better than stock and works great, but it doesn't keep the door shut all the way like a pop-valve (grainger type) and it costs a lot of $$. These valves are cheap and work well. You can even set up a multistage boost controller with them for less $$. I am making a 2 stage (low and high boost) for my 87 TII. Read this:

and look at the links here.....even though it's Mopar stuff, it still applies....

There is one for the MAP sensor too (FCD). I have one and it works better than the generic FCD's out there. There is no electrical change to the ECU either!
Hope that helps

Airpumps don't operate at WOT so I don't think it would work. I don't think they "pump" nearly enough air anyway. NOx is pretty much the accepted way to go, forget about rally style anti-lag, that stuff is not streetable
