Not stock, but idle 39-40 lbs., WOT 63-65 lbs. I will look around for stock measurements using 24 lbs injectors.

I believe it should be around 40 psi differential pressure between the intake manifold and the fuel rail. So if you're under vacuum it may be less than 40. If you're under boost it will be over 40.

Cool. Thanks for the info! I was hoping it would be around that!
