I've logged what I thought to be the correct channels for injector and fuel pump duty cycle. 4.8-4.9 ms converts to about 25% inj. dc. I would assume that would be times two for both banks? If so the factory injectors are plenty big for a 10.6 @ 130 mph pass.
Not sure I believe fuel pump duty cycle at only about 15%. Only channel I could find for my 2017 C7 Z06 that has to do with fp dc.
