Fair to call GSSL "Turbo" mod- Dual Mono?

It seems to be true... just curious if I'm missing something???

No -  the L/R are still linked.  The control voltage from both the L & R are taken independently, but they are summed before going through the attack / release (I think). So the compression on L/R is the same. Dual mono would need separate paths for the control voltage through attack release and seperate cv to the L/R. 

Since you can't set two different ratios, attack times, release times, thresholds or makeup gains... no.

It's still a single stereo limiter, but HOW the detector determines its control output is achived by a DIFFERENT analysis of the two channels, that's basically all.

In the original GSSL left and right channel are summed for the sidechain. So the in-phase signal component (in M-S terms the M component) affects compression with twice its amplitude, the out-of-phase component (S in M-S terms) nulls and thus affects the sidechain not at all, and anything just present on either of the channels affects compression at its own amplitude, and thus half of the amplitude as a signal present on both channels.

To correct this uneven behaviour the turbo modded GSSL has circuitry in the sidechain that - untechnically speaking - looks at both channels and always uses whichever has the highest amplitude. Thus phase or pan position don't matter.

Dual mono on the other hand would mean that each channel is compressed seperately according to its own amplitude - which is not the case here.

So, would having a "dual mono" sidechain be an advantage in any way?

Well, you could compress two mono signals independently of each other, albeit with the same compression settings. But it wouldn't work as well (or at least differently) with stereo signals, the task the SSL mixbuss comp was designed to do.
