Closed loop boost control

Turbotech, not Fierotech, but it'll be fine.
I own a fair number of turbo cars, but most of them are factory turbo cars that I haven't modified, so pardon my ignorance.
I was watching a video on Haltech's youtube channel about closed loop boost control and holding a wastegate shut longer to decrease turbo lag and increase power under the curve.

The results are pretty impressive, on a ~310HP car they saw gains of around 20HP throughout the range, and on a higher boost setting they saw up to 60HP gains.
I do not have Haltech, nor do I have standalone. But GFB (and many others I'm sure, GFB happens to get good reviews and the price is good) offers an electronic boost controller that claims to do closed loop boost control.
Are any of you running an electronic boost controller? On my Skyline I have always thought the car was laggy, and was curious if I could employ this technology to make the car more responsive. Car currently has a turbonetics bleed valve on it, but its wound all the way shut because the car has 1bar wastegates on it and ~15psi is all the more I wanted to run untuned (have a Blitz chipped ECU in the car). The car does NOT have stock ceramic turbines on it, it has larger than stock steel wheeled twins.
This is a long post, but basically what I'm asking is, could I see any increase in response using an electronic boost controller on turbos operating at their wastegate pressure? Or does this strategy only work with a custom tune and running boost pressures above wastegate pressure.
