Anybody have a pulley on a series 1, ssei, I have had mine on my car for 2 months now, I have an autometer boost gauge and I still use the one in my dash. The one in the dash moves around a bit when my car is idling at a light or running in the driveway, it doesnt get out of the -70 side, usually stays below the first bar, is this normal or should I be worried about something?

could just be a problem with the dash contacts in the back of the cluster, or a problem with the cluster itsself

Could simply be WHERE or HOW you attached the vacuum line to the other gauge. Try hooking it up in different locations. Your OEM boost gauge is acting normal.

Moving to Forced Induction.

Where did you put your vac T for the gauge?
