Injector size for higher fuel pressure

Post by Dirmaid » Sat Oct 17, 2015 10:11 pm

I have an 01 Ranger that I'm supercharging. I have 36 pound injectors that I will be putting in, but these are rated at 43.5 psi and the truck runs between 55-65 psi stock. This would put the injectors at an average of 42 pounds. My question is, do I put in 36 pounds or 42 pounds in the drop down menu? I'm not sure if it compensates for the higher fuel pressure or not.

You would need to choose 36# in the drop down.

So after installing the new injectors and putting the tune specifying 36 lb injectors, I was idling around 12.5 afr with it missing every now and then. I pushed a tune with 42 lbs specified and it idled correctly at 14.7. WOT shows target afr as well. Just thought I'd let yall know that I needed to put in the calculated flow rate at my fuel pressure instead of the advertised one
