Have used 750cc Bosch in a car before but never really took that much notice of them... they were from 034 and appeared to be a hacked 550cc as all the PN's were the same...
http://www.034motorsport.com/fuel-injection-solutions-fuel-injectors-550cc-or-750cc-bosch-ev14-fuel-injector-p-17564.html

I did consider running 550's at 4bar instead of the 630's... can't say I have noticed too many issues with them and in the 20k+ miles they have been fitted and through the various changes to the engine they always come out clean but then I have had a PCV delete since day one of my build...

Had a hunt around for the specs of these but couldn't find anything... intrigued as to what they do to make them flow more and how this affects latencies etc...

All 750's are modified 550's FWIW.

My experience with them has been pretty good so far but who knows how different people modify them in order to obtain that flow.
A certain someone said they are (re)drilled to obtain that flow.

For reference:
550's @ 4bar = 635cc (or 638cc) and should "work" with most 630cc tunes but YMMV.

I recently tuned for a set of ev14s custom blueprinted to flow 630cc@3bar. The spec sheet that came with them was perfect. Plugged in the values given, trims were the closest to 0 I've ever seen. 10th of a percent.
