[Hi-Rev]

Well later today on the way to work I hit full boost a few times to see what would happen and no beep. But I got off work tonight and hit full boost coming home once and it beeped. Its not a beep beep its a long beeeeeeeeeeeeeeeep until I let off. It sounds like it may be the gauge though. I have an autometer black faced 52mm 20psi gauge. It glows blue also. Thing is before I installed the controller/gauge I had the free boost mod done and no beep ever. After boost controller/gauge it even did the beep at around 12.5psi. Maybe the beep is when the boost stabilizes at full boost on the gauge since it only does it when it hits full boost. Anyone know? I guess I could hook up my friends logger and see if its knocking. If not it has to be the gauge.
