I wonder if you're stock diverter valve has taken a dump. They are largely made of plastic and known to fail under stock boost over time, let alone increased boost pressures.

The GFB DV+ would be a nice upgrade and reasonably priced at under $150 shipped. Might be worth a try.

Interested to hear if anyone else has any ideas.
Done just got the exact one you recommended. I will keep the thread updated
Just a word to the wise... there are a lot of knockoff DV+ floating around.

Just trying to save you the trouble of dealing with it.

I hope you purchased from a reputable dealer. This is one part that you dont want to buy at discount. That likely means its fake. For example... you can find them for around $70 on eBay.

YouTube it and youll see what I mean. Also this forum outlines the issues people have had.

Can be harmful to turbo and will cause you to take the car apart twice.
Bought mine straight from KieMotorsports. I'm pretty sure his company is very well known here, so I suggest OP buys from him.
You are correct. I got mine from Extreme Power House who is also a forum sponsor.
Yeah I bought my BM3 license & ER DP from extreme power. So I agree also.
