well, im hard headed so i went to iroczone and used their injector calculator to find out exactly what size i need. and at 450 hp at the crank it says i need 42's to run under 80% duty. so i guess everyones right. i just need to suck it up and get some.

IROCs run 43 psi of fuel pressure unlike our 50-58 psi regulators. We get even more flow from the injectors than they did. I'm not sure what calculator you used on their site.
