I found this interesting bit of information at
http://www.injectorcleaning.co.uk/flow.htm
Bosch Part Number: 0280150552 (crossref to 1992-98 Audi 12V V6)
156 cc/min @ 3 bar (44.1 psi)
Resistance: 15.9 ohms
Audi typically specs their fuel rate at 43.5 psi so 3 bar is close. I'd expect the installed flow rate to be about 150 cc/min.
