Typically this pump will flow 30% more than a brand new Bosch 99.5-03 pump, which is plenty enough volume to sustain 250/100 hybrid injectors. 250/200's can be ran with this pump, but it is not a guarantee that it will keep up in a "hot/race" tune as there are variables between injector builders on how well they build them.
This pump is more recommended for 230-250cc hybrid injectors. Anything larger will more than likely require a larger pump setup.
These pumps go through rigorous bench testing and normally flow 30% more volume than a new Bosch 99.5-03 pump
