Gtm supercharger stg 2 bpv stuck closed?

Funny you mention that (not really funny) but I had the same exact issue about stalling. Turns out there was too much fuel in closed loop idle on the tune. Once the fuel was pulled, it sorted itself out.

Whoever tuned your vehicle, you should have them do a live data log at idle when the car is warmed up and adjust the air/fuel as needed. You could also have them slap it on the Dyno and if they can "Tee" in and check boost levels if their Dyno is applicable for it (if you're worried about a boost leak or BOV becoming stuck).

Once I get my boost gauge I should be able to tell if I have a leak... As for the tune, it was GTM that did it. I data logged the car, sent them the info, he pushed some buttons, and sent me a tune ( repeat a few times )... It might have been an isolated case. Sub freezing air plus rapid decompression caused by bov might have caused the vapour to freeze on the unit... Will have to test more once it stops ******* snowing..... But still, an essentially brand new bov should't be scored up already.

So an update... It's nice and warm out, I am almost certain it is stuck open as I can hear it venting even while under accel. And the car is running super rich and has much difficulty staying idling.... So I figure I might just try to clean up and lubricate the turbosmart bov/bpv ( not sure which it is) but it really should not be acting up with such little use on it.....

Any suggestions on action that can be taken would be greatly appreciated.


Update I had it running (barely) out in the shop. At idle the bpv was closed, and the air fuel ration according to my laptop was at a steady 10.000 : 1 so that is really not good.
