By the way Greddy turbos can't do 10 psi with stock injectors. The Greddy kit comes with RC 550 injectors. I think stock is like 360??

 

I ran 8.4 psi non aftercooled for a year on my comptech with no problems.. The FPR tune is going to suck though, 10's in the lower RPM's and mid to high 12's in vtec..

 

That’s true, more so for the f20 due to how it consumes fuel with the ap1 fpr ramp up. Vafc is one way to solve this if you want to keep the factory injectors and not spend a butt load of money. I still use this set up myself. It does the trick nicely. The OP has an Emanage though so this is irrelevant.

 

greddy kit uses upgraded injectors btw
