    Asked by: Zeke01rebel
    No, this cam is too large to be used with a TBI system with good results.

    Would this cam be safe to use in a TBI application ? I see it says computer controlled compatible. Is this cam too hot that I'd lose vacum and It wouldn't idle ?

    Asked by: Leftypro300
    This cam will not work for TBI application.
