Had mine flowed at 315cc. I think they flow test them at 25PSI? Which may or may not explain the descrepency.
There are a tonne of online calculators that give injector sizes dependant on a number of variables. The one below isnt the best, its just the first I found on google.

At 177.5bhp at the wheels I run ~85% injector duty cycle on an NA engine with what I would presume would be a very low BSFC.
