read this through, and found it interesting.

"I just recognize that the process of modifying the injector has the POTENTIAL to screw a lot of things up. Some companies do it blindly and just copy/paste injector data from some other source and hope that their customers aren’t discriminating enough to tell the difference. Other companies recognize the effects of each modification and go through the trouble to do the same SAE-spec testing to completely characterize their product and deliver good data along with the hardware for each individual part."


"As a specific example, Injector Dynamics uses the same Bosch injector body as the starting point for their ID850 fuel injector. A key difference here is that the ID850 flows about 12g/s (98 lb/hr) at 4 bar, so we’re looking a a huge step away from the stock flow rate with more than double the flow capacity. It would stand to reason that such a drastic modification would yield even worse results than the mildly modified samples we saw earlier if one were not careful. This is where it gets interesting. Injector Dynamics not only provides accurate, complete characterization data for all of their parts (http://www.injectordynamics.com/ApplicationData.html ), but the parts themselves are more consistent than other redrilled examples."
