Thread: Boost Bypass Valve is forcing boost at idle and reverse.

So after discovering my BBV had a leak in the bottom, I bought a new one at ZZP for 65$. Replaced it today and I am completely fathomed. When you fist start the car the BBV is OPEN in the up position, seconds after it starts it closes allowing full boost at idle. So for sh**s n giggles i set the e brake put it in drive and its in the UP position or OPEN like its suppose to. But somehow reverse, park, and neutral its closed forcing full boost. whats going on? is it my pcm telling the solenoid to open prematurely?

Did you connect the vacuum lines backwards? ($65 for a BBV?!)

No, im positive they are right I tired reversing them to see what would happen but it did nothing. I meant BBA boost bypass actuator, to get the solenoid mount it was 15 bucks more.

Full power in Reverse?

I vote for a video of reverse donuts before this is fixed.

Second that vote

Third on that one! To add to that, put in some reverse burnouts! Or maybe even drag in reverse :P just kidding lol

I dont know about a reverse burnout but if someone can tell me whats going on ill burn sum rubber off on vid and post it lol.

dont do reverse donuts, its very bad for the tranny and the axles. then you'll have real problems.

I meant regular burnouts in drive, getting new tires anyways
