I bought the 19lb injectors from fiveomotorsport (P/N 0280 155 909). These are gen 3 injectors from Bosch.

I am sure the rating is based what fuel regulator pressure. As I am using a 3.5 fuel pressure regulator, found the car to be running rich and experienced extremely high fuel consumption. I must say, the low to mid torque improved significantly.

I will try to install a 3.0 bar pressure regulator this evening and see how it works.
