1000cc injectors flowing at 900cc?
Not getting too much help over in the Tech section...it is going in an FI motor.
I just got my injector flow test results from Rich @ cruzinperformance.com, great guy by the way, and they flow ~900cc! These are suppose to be 1000cc precision injectors but they flow less than that. Good thing is that they are pretty close to each other. I looked up the part number on the injectors and they are 1000cc.
When i tune should I input these as 900cc injectors? or keep them as 1000cc?
here are the results...

They were flowed at 43.5psi as shown on the test results. I believe this is the same psi they are flow tested when new to 1000cc.

Its not really a secret. Most 1000cc injectors are not really 1000cc injectors

Re: (SOHCD16y8)
I guess I should be happy that my evoVIIIs flowed out to exactly 560
I'd run them at what they flowed according to the tests. So at 43.5psi just treat them as 900cc injectors.

I havent tried calling precision yet. Should I? Do I need some kind of proof of purchase?
My base fuel pressure is at 55psi at which would make the flow rate at around 1000cc. I had a hard time idling these. Would them actually flowing 900cc cause this?

I am not sure anymore but according to the part number on them they are 95lbs.
Should I run these as 880s?
