you run whatever your chip maker says to run....generally 40-42 lbs line off

oh ok, thanks I was at 43 line off. I had forgotten to check it after the 50# inj install and when I looked at it tonight it was at 30psi.

What did it run like when it was at 30psi?

injector change shouldnt change your fuel pressure

you did pull the vacum line off to check it right ??
