Most people calculate Inj wrong and dont allow for an Injector shouldnt be run past 90-92% duty cycle , Its always best to run a larger Injector then is needed

Is there a point that it should hit on the low end? i.e. running an injector say below 40% duty cycle? if not it would look like the best thing is to just always get the largest possible injector and juts make sure your tune is adjusted for it regardless of 150HP or 450HP...

You dont want to go overboard on the injectors but best to go larger

not enough injector resolution, run to large and you'll see this. Very few ppl have this issue though.

btw I've had stock injectors up to 240whp, gotta run a return fuel system and shit ton of fuel pressure. It was just a test to see how far I could push them.

I currently run ID1000's as a few others do on here as well.

Using the calculator it looks like 60# is good to about 350HP under boost and then you need to start looking at a return fuel system along with the 60# injectors.
