edit. I just looked, they do not have a boost chart that I could find, what they did have is a troubleshooting guide and 1 of the troubleshoots was " Engine has vac at low RPM " and it said it was normal when not under boost. right there compleatly confirms what mike said, now all I got to do is show him so he belives it . if he runs a vac can with a check valve behind it, that will give him the vac he needs right? thanks
he can put a can on it if he want to but he don't need to. i never ran one with 454,671 set up.
