When logging fuel rail pressure C7 Corvette.
Is rail A passenger side and rail B driver side?
My rail pressure is about 25 psi lower for rail B.
I believe I have a leaking injector and before purchasing a new one, I wanted to verify rail side.
Thanks
There is 1 pressure sensor. Maybe "rail b" is an inferred value

looking at your logs they look exactly like mine did with the wrong size lash cap failing the HPFP or you have a injector with a busted seal. Is you engine ticking? both times my HPFP failing after about a week of DD it. It would finally start chirpping like a lifter went bad. But before it started chripping my STFT 1 and STFT 2 would look just like yours. Where one would be 8 and the other would be -8 at idol. They where always 10 points different or more.
I'll try and find a log to show you.
Look at this thread I started with some of my logs. You could have a blow injector seal too. I kinda of fixed both at the same time. Either way it's the same amount of work to get to the parts.
