as with all the info on injectors it's pot luck whether they can do what they say.
beiges flow at 226cc and they get used all the time for around 200bhp along with a 195 chip, however what is worrying is that they shouldn't even be able to run safe at that level.
in fact on a turbo engine not running monster power they should only be able to push out around 47.5bhp each, so a total of 190bhp and that is a well tuned engine with a BSFC value of 0.42.
but as we learn a lot of engines with levels of mild tune don't return that value, so knock it down a step to a BSFC of 0.47 and you get 42.4 bhp per injector, so only a total of 169.6 bhp and i'm taking the 95% duty values which isn't ideal as you really want to have a max of 80% to allow for variance in air and engine temp to fuel adequately across the ve tables (this would now be 35.7bhp per injector)
think about an even worse engine with a worse efficiency, the rs turbo engine as standard for instance could possibly have a BSFC of 0.52, you can see where this is going, for a safe setup this is roughly where you want to be planning an engines fuelling with duty cycles of 80%:
32.3bhp per injector now, total of 129.2 bhp, this is for a lightly modified engine.

i've done this little write up to show how inappropriate injector sizing can be sometimes and that there is little room for movement on some setup, in this case beige injectors really are pushing their boundaries on a daily basis when fitted with a 195 chip as a package.

to put things into perspective the 60Lb injectors myself and Karlos have chosen will flow enough for a duty cycle of 80%, fuel pressure of 3BAR (these can run 6BAR salefly though) and a BSFC of 0.52 for the worst cas escenario will fuel enough for 92.3bhp per injector, enough to fuel our engines at a minimum of 369.2bhp, this is taking safe calculations etc.

look at the bottom of this link to show the flow rates and power output of a particular size of injector:
