Food for thought; does having a single WG on an elephant trunk negate twin scroll?

So far the only noticeable difference in boost treshold, response (lag) and precision come from dual-chamber wastegate control, where upper chamber is controlled by electronic boost solenoid (which is controlled by ECU or EBC).
We have tried both stock 930/931 units and Tials and to be honest never seen any difference other than Tial being lighter.
With stock unit boost is absolutely steady and both chambers are perfectly controllable. No spikes, creeping, fluctuations, nothing!
My Gulf race-car runs at 0.8 bar base pressure which is adjustable with a knob that sends 0-5V signal to ECU (VEMS) which controls the boost solenoid and I can turn it up to 1,5 bars.

Thanks for the inputs guys.

Interesting perspective Brian and what I was looking for regarding lower boost has less effect than higher.
