The OEM injectors are calculated to be at 100% duty cycle to produce the factory advertised 215 hp, IMO this is why the stock xfire falls flat in the upper RPMs. My car definately pulls harder from 4000-6200 rpm after switching the injectors.
The calculator may be off but I believe it to be accurate.
