as a first step you might fit a bigger CC pump, e.g. a CWA50, two of the m in series or a CWA100 (Pierburg). A Bosch pump will only give you some 7l/min through a PWR barrel charge cooler and 19mm pipes. Maybe a tad more in a front install.
Have you measured air and water temperatures before and after the CC? without that it is hard to say where the bottle neck of the CC system is.

Regarding jets. If you can remap the car, I'd consider 6x direct port nozzles right behind the fuel injectors. Avoid any turns for the spray.
if you cannot remap, I'd consider pre-turbo 0.3mm or 0.4mm jets, one for each turbocharger. This will give you mainly charge cooling with litte condensation. Most of it will evaporate in the turbocharger.

i'd not do a single jet with that topography.
