Troubelshooting: BOV Opening Under Acceleration

Well, When I had my car tuned. It would lung forward when i did the break/ebrake gas thing... Soooo
You should bulk up your left leg then.. lol. Cause I apply a very heavy left foot and the car does not move.

My brakes are quite stout though.

You need to view the desired boost vs actual boost as well as actual waste gate vs commanded. That's the only way you will know if one of the BOV's is failing. That way you have factual data to compare. Just listening to it won't be enough.

The only simple/quick thing I can think to do is have someone in the car, apply parking brake, put the car in gear, do a standing brake boost to full throttle while you hold your hand by the BOV to see how much boost is being dumped compared to the front bov.
I set up torque for the first time this morning and did not see any gauges for the option of desired boost, actual boost, actual waste gate and commanded. Is this something that can be monitored?
All I can confirm at this point is that the car never had audible noise from the BOV while VTA while accelerating before I got it back from the dealer. Something has changed since they have had it and I just want to help point them in the right direction once the dealer techs start looking.

There is an entire thread on this in the datalogging section (desired boost vs. actual boost)

I think 4WD is a more likely explanation.

Yes.  Lol. Just giving you a hard time.

Do I have to pay you? *bites lip*
 
To the OP, I'm sure you've already fixed this issue, but in case you haven't, check this hose.  It is right behind the front BOV.  Mine came off while I was moving the charge tube around to change spark plugs.  Never noticed it.  Drove the car afterward and the BOV's were constantly opening and closing under acceleration.

Holy crap this thread just saved my bacon.  On my way to work today, I got on the throttle and the car made all kinds of awful noises, BOV was venting weird, no power.  Had a minor heart attack, thinking something majorly broke.  Happened to read this.  Went downstairs and sure enough, this hose had popped off.  Phew... Thank you forum gurus.

I would get Brad to come over right away and clamp down those hoses for ya :P

You joke but I do need to clamp it.  The hose keeps popping off, lol.  When I looked at the end of the hose there was a layer of wet black oily gunk.  It's all slicked up so the hose slides right on and off.  In addition to the clamp, it looks to me like its time to invest in a catch can...

It sounds like you were spared in the heat of the moment! Glad you caught it on time .  :)
I used some 1/4 - 6mm Hose clamps to fully secure all of the wastegate Hoses which worked like a charm .  Z
