    Default Profec B Spec II tuning problems

    Okay,

    I'm making an attempt to program the boost levels so I no longer control the boost with my foot. There is simply not much change upon following the directions in the manual. Still overboosting!

    Is there anyone in the wylie area that has programmed/set a Profec B Spec II boost controller? I need help.

    Keep in mind, this is my first FI'd car and I didn't build it...

    You sure the wastegate is functioning properly? Most of those EBC's are pretty intuitive. If I was able to set up and use an AVC-R, anyone can :-P

    Mine was a blown diaphragm in the wastegate. It's a good place to start.
