Unfortunately, the setup does not use an electronically controlled bypass valve - its actuated using vacuum. Since a blower is mechanically connected to the engine, you really can't run into a high boost situation - unless your pulley is too small. The bypass valve is really just there to help with idle conditions as far as I can tell.
Well shit....i was onto sunthin I thought haha. I was just assuming the bypass was pcm controlled via a valve and vacuum. Most things like that on newer cars are ran by pcm. Guess not in this case lol

I know on my 2016 VW the BOV is actuated by vacuum still but the pcm tells it when to. Sometimes at real light throttle going up a slight grade you can hear the pcm opening the bypass for w/e reason. Sounds like a procharger race valve lol. The pcm in that thing will also use it for torque management and traction control. You can be WOT and this thing will just blow off all ur boost till it shifts and stops spinning so bad.
