Yup, he's the current owner of this car!
I've seen some crazy posts on here too, that goes for a lot of forums. I love the ones that are totally random... like a post on Volvospeed about a problem with the guy's Dodge Ram
It's the original Pierburg TCV. It's probably in need of replacement.
That's the thing, for the longest time with this car, I never had any problems with the TCV. Or any other P80 I had early on, but now it seems TCVs are dying left and right. Which is funny, some people say they never have problems with them, and others do. I probably have 5 or 6 on the shelf, and they're all over the place. I had one that overboosted like crazy, and one that capped the boost on my V70R at around 6 PSI. That one was the gray Pierburg Porsche one that is a common "upgrade". That was not my experience with it!matthew1 wrote: ↑17 Jan 2020, 13:41 My 850 boosted well beyond 12psi as measured by a new iPD gauge with a stock TCV. 17-18. I don't recall ever changing it anyway... my memory of my 850 upgrades isn't perfect. I don't see anything in my email which goes back to 2004 with "tcv volvo" so I'm 98% sure I never upgraded it.
Ordered a new OEM Pierburg from FCP and boost has been stable and where it should be on my R.
