Just a quick one, does anyone know how the 6G74 and 6G75 fuel injectors compare, with regards to impedance and flow rate?

They're both high impedance types (13-16 ohms as I recall).

The CDH-275 injectors used for the 6G74 are valued at 268cc/min in the ECU code, and some googling turned up a reference to them being rated at 284cc/min (but no reference to fuel pressure for that rating).

That same reference suggests the CDH-305 injectors used in the 6G75 are rated at 308cc/min - ECU value unknown. These injectors have a different nozzle pattern (12 jet vs 4 jet for CDH-275).

Intuition tells me the part number is an approximation of the rated flow rates??

I'd be guessing you are right, my original 380 injectors were flowed at 305cc which is the same as the part number.
