is the SC light kind of dim? as in not as bright as when its normally boosting? I'm not to sure what that problem may be as I had that same thing but I was having issues with my SC not boosting unless I turned off the car and then turned it back on. The problem with the boost went away along with the light issue...so maybe it was a relay for me...check the relay? HTH

The SC indicator lamp is directly triggered by the AFM reading. The fact that it remains constantly on and you are burning excessive fuel points to the AFM either possibly being stuck open, or it may be defective.
