Your cam between 230 to 242 duration and the 60kpa is normal ,just make sure you get LTFT Boundaries RPM & MAP correct so you can get good idle vaccum..

perfectly normal, what engine is it btw? We got a SLIGHTLY bigger cam on a z06, and it idles around 61. I cant remember but a few changes took it below 60, idle rpm, idle airflow and a few things if i recall..

It's an LS6. I just wanted to know what is the correct value. I suspected that I have a vaccum leak or something. Was going to tear down things......
