oh, another thought. i wouldnt drive that car hard untill you get the vacuum line to the FMU fixed. if you arent getting boost pressure to the fmu, you are gonna be way lean.....dangerous...
oh, how did you check that you had pressure at your bypass valve? you could also pull the vac line off the bypass valve to see if there is vacuum on that one too.
the bypass valve keeps the impellar from hitting the volute (houseing) when the throttle plate closes and the pressure spikes between the blower and the throttle body, but the fmu working properly will help to save your motor....Last edited by SS#1230; 11-14-2008 at 12:31 AM.
