155 bar T/D injector mileage.

[Rabbit TD]

Do the 155 injectors with factory nozzles give the same mileage under the same conditions that the 134's do and is there actualy a difference in the nozzles or just the breaking pressure.  Either way do they affect mileage compared to  the N/A ones?  I don't have any problems, I'm just curious if there's a difference.
