I like to tap into the FPR for boost gauge. This way if a line pops off you KNOW you have an issue. Most people watch the boost gauge. Most people never look at their fuel pressure gauge (if they even have one)

Here is another thing i noticed. When i pull from 3k in 2nd or 3rd. It will bounce back and forth between 15 and 17 psi. I am keeping my foot steady on the pedal. Is this an indication of a problem?
