I can offer nozzles for 2.5 V6 engines.If you are running something bigger than the original turbo you need fuel.NOBODY can tweak VP44.So the right way to go is nozzles.I can offer two different.The first one is 8x180 -66% more fuel but when you remove the pressure drop from the pump it's really 50-55% which is good for 300-320hp.For the very power hungry i can offer 8x190 which is 88% more fuel.-really 70%.This is with the same spray angle.They are custom made.8 holes mean better atomozation and more power.
