Default 1000cc injectors flowing at ~900cc?

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...

what are you tuning with?

when you "input" the injectors, in most cases, all it does is scale all your fueling up/down by watever % change of stock vs watever u put in. so if they flow 900cc, id put in 900cc

big injectors are always harder to tune the idle, imagine trying to water a small plant with a fire hose

have you messed with injector battery offsets and the main offset multiplier?

I set the injector battery to the 1000's and played with the multiplier but it would run very lean or very rich with only 1% change in fuel. WOT was fine though.

No its not why.
Try another ems & you will see idling 1000cc injectors won't be such a task as it is with crome.

What was the fuel pressure during the test? If it was the same as the fuel pressure on your car, then used the measured flowrate.
