As far as the stock bpv not holding boost, I'm curious as to how you came to that conclusion. By design, it's just not possible. If your stock bpv can't hold boost pressure then either the diaphragm is torn or something else is going on.
I was getting a p0101 boost leak. Was like wtf looked nothing no cracks or loose piping. my rpd wasnt agreeing with the code and it would go limp mode like every few days till i shut the car off about 3 times. Then it made sense i got a bpv code with in 2 weeks. Im thinking the spring was just weak so it was "rolling to the side" under boost causing a p0101 at first. Then the car figured out it was the bpv. Changed it to the forge no issue since. Just a the drag strip for lack/overload of grease lol

Yeah ive had it for like 4 months now used about 2 table spoons worth using it for other stuff as well lol i just picked it up reading thats what Forge says to use. I just dont get how ppl run it for 10k+ miles befor re-greasing it and i get a code 3 times in 4 months for it they must not run there car much/ hard lol But again only the drag strip where im sure its getting hot as fk.

When u take it out clean it really well dont take it off the turbo just unscrew it where the hose connects. Make sure there isnt to much grease under the orings or on the end of it. I threw a little inside it and on the plunger/orings this time and code went away by itself so it must be cycling right

No not where the spring is but the inside of the housing that stays in the turbo when u unscrew it thats what holds the spring so be carefull after that take ur finger slide the plunger out put some on the plunger/orings and some on the inside where it goes back in you will see when u take if off then slide it in a out a few times by hand then check it to see if its gunked up to much . i pretty much only re-grease it after the drags lol cuz of the codes driving around 2 months no issue till last Saturday at the strip. Being to light handed made it where off very fast o didnt put any on the inside befor this ether just the plunger so im thinking there wasnt enough to keep the heat incheck and it faded away

Make sure the grease is good for low temperatures too. Wouldn't want it getting stuck and the next weakest link in the system going pop.

Luckily I haven't had to re-lube my forge VTA yet. Around 15,000km on it and I'm pretty sure the VTA would go through grease faster than the BPV will.
