I saw someone selling some DeatschWerks 525cc fuel injectors in the FS/WTB/WTT thread and it raised a few question that i'd like to learn more about, being that im not an ancient motor guru...

I looked up the specs on them at the DeatschWerks website and saw that they also come in both 525cc as well as 450cc. What is the technical/non-technical difference? Pros? Cons?
Also, here are the product details along with a couple of my questions:

-Flow rates and set balancing in-house by DeatschWerks Whats a general Flow rate of a D17a2?
-Flow balanced to within 1-2% (flow report included) Elaborate on this..?
-High Impedance coils to match OEM ECU
-drop-in fitment (connectors with pigtails included at no additional charge)
-Excellent spray pattern and atomization for excellent idle and tuning
-Technical assistance and tuning data available via phone or email
-12-month comprehensive warranty


Lastly, are there any other injectors one could buy that out-perform stock injectors, but can also be used in a stock motor?

 

It is my understanding that the DeatschWerks is a Denso based injector. Just like the RDX injector.
You may also want to look at a Bosch based injector, like FIC or ID's. Fuel Injector Clinic or Injector Dynamics.
RC, is another but there injectors are of the Lucus based design and have a limited spray pattern compared to the Bosch and Denso designs.
I'm just looking for dyno comparison of the DeatschWerks in a NA application before and after.
