Wow! So much BS and posturing in this thread! A couple of people are spot on. What test fluid was used? Makes all the difference in the world. I built a home made flow bench, and have used a couple of different fluids, and have tested all kinds of injectors. The results are always different from one manufacturer or another, due to fluid. I have flowed a bunch of stock injectors, in order to get some relative flow data, and create conversion formulas to compensate for this.
The hard truth is that there are actually only a few manufacturers of injectors out there. Siemens is one of the most major. These injectors were designed for OE applications, and as a result, flow rate differences between injectors is tightly controlled, therefore your tolerance is tight, which your flow tests indicated. That is as important as overall flow rate for the set.
I'm not going to throw any fuel on the fire with my own numbers, but as a tuner, I know which types of injectors work as advertised, and which ones are a bunch of marketing hype. WAY too many of you are taking the hype, hook, line, and sinker. I have dozens of injectors around here, and these Siemens are what are in my car. Given that I have more than a cursory knowledge of these things, and that I have access to whatever type of injector I want, does it surprise anyone why I would want to use these?
BTW, I sell tunes and traction control devices. I do not sell injectors, or any other fuel system component. I have no dog in this fight, other than to know what works, and which components are hype and/or junk. I advise my customers accordingly. They can buy from wherever they like.
