Contour Enthusiasts Group Archives Forums Modifications Forced Induction fuel pressure, again...

I think you are missing the point.

1. He was told by other people his fuel psi was too low.
Why was he told this? Did he just up and check his fuel psi for no reason or was it because he had a problem that he was trying to track down?

2. He says he has a lean misfire. He's changed everything to include the pump, screen, filter, to include reflashing his code back to stock. He doesn't know it is a lean misfire, he just has a misfire.

The result of these facts means he should reevaluate what his problem originally was, if it is still the same, or if it has now changed. Then come up with a plan of attack.
Now if he does this and everything (after ruling out the common issues) points back to fuel psi, then by all means pursue a fuel psi issue.
