Default Re: On the right track?

i would drop the current nozzles and go proper direct port.
Injecting a lot of mix through pipes and intercoolers leads to condensation and big droplets passing through the engine with little effect.
The exception to the rule is the very fine mist air assisted nozzles produce.
Some of this mist making it to the engine.
But even Riceracing also installs direct port systems these days if more suitable for a particular application.

the charge dilution from vapor is outweighting the gains from air desnity increases due to temperature drops.
this is one of the reason why the car gets slower.
also injection water without tuning virtually always leads to power losses.
Water slows combustion speed. you have to add timing.

I suggest you try to stop getting hung up with IAT drops and focus on what makes power.
