I also did a log pull afterwards and I noticed a 0 duty cycle. Soooo vacuum? I also performed a proper smoke test... No leaks. The impeller of the turbo looked great. I do suspect either the pressure converter (epdw) or the diverter valve. I have attached a link to what the car sounds like under load. Please let me know what you think!

if your intake is injen then i think it's normal sound, i have a problem where my car consumes oil and i don't see any thing from the exhaust. aside from that the car runs great

Can anyone confirm if the factory Diverter Valve on the N20 motor can hold 21 psi of boost? If not can I just buy an uprated spring to make it work?

Thanks!

I think if you're going that deep (swapping springs), you might as well go with a proven upgrade...........
