It all depends on how it's connected. As it sits now, it will introduce constant 3 bar pressure difference across it's two fuel connection (and actually compensate AFR for barometric pressure. Neat, huh?).

Once you connect the hose to it:

If it's connected so it increases control pressure with boost, the effect will be that your boost AFR will lean out and your trailing throttle will get richer.

If it's connected so it lowers the control pressure with boost you will get even more boost enrichment and more leanness on part-load.

If first thing happens, you'll get the behaviour that you want (which is good) but base map might be shifted after all your fiddling. Thus you might get consistent 14:1 AFR both on boost and light load. Then it's just a matter of lowering the control pressure until it's down to 12's and you're square.
Thank you for your time,
