Underboosting?
I was just out for a drive and decided to get on it..and when I did it felt like I barely stepped on the gas. Look over at my boost gauge and I'm only hitting like 4-5psi..wtf?? Yesterday I was 13-14. I'm at work now so I can't really look at anything until I get home but anyone have any quick ideas of what might be wrong?
I have the Greddy Profec B Spec II boost controller. I'm thinking a line came loose somewhere, but wouldn't that cause me to boost at wastegate pressure at minimum? I know my turbos are 4-5 years old, any chance one or both of them have just gave out?

Well it involves a certain someone unknowingly pressing a button on my boost controller at some point, changing the boost controller to a preset setting that had, well nothing set to it essentially turning off the controller. This certain someone of course was not me
