Re: 1997 850R - Stumped - Boost Issue **Solved**
Update: Well, the stock wastegate went back in and now everything works! Not sure why the previous attempts didn't fix it but maybe I had multiple problems that have now been fixed. I am so happy its working again but at the same time disappointed that a part that is supposed to work doesn't. I am a...

Re: 1997 850R - Stumped - Boost Issue
Yes, BOV is accounted for in the tune. I brought my OEM Wastegate to work and will probably put it on at my lunch break today and test it on the way home. If its still the same then I guess I will have to save for a turbo

Re: 1997 850R - Stumped - Boost Issue
The flap opens and closes super easy with the arm not connected. One thing I just thought of yesterday is that even though I have a Blow Off Valve, there is still pressure being released to where I can hear it in the intake along with the BOV. Is that normal? Also what about the cap and rotor being ...

Re: 1997 850R - Stumped - Boost Issue
Maybe it's time for an 18t upgrade for "testing purposes!" If I could I would. I hate being broke all of the time. But wife and kids come before my car I guess. :) I hear ya... it's not fun trying to do my V70R M56 swap with no money! Fortunately no wife or kids for me to worry about yet....

Re: 1997 850R - Stumped - Boost Issue
Thank you all for your replies. I put the OEM wastegate back on a year ago maybe and it was doing the same thing. Maybe its time I try it again to see. And, yes its the one from ARD. You know, I wondered about the actual Wastegate flap in the turbo myself. I was hoping to never have to remove it unt...

Re: 1997 850R - Stumped - Boost Issue
It has a Blow Off Valve now, CBV is in good shape but in a drawer in my garage. Just put it in to check out if the BOV was an issue.
I did also do a MAF swap and it was the same result.
Yeah, not sure if O2 would be an issue but I would assume I would see a fault code for it.

Re: 1997 850R - Stumped - Boost Issue
Yes, I have a Stage 2 tune from ARD (see signature for mods). Have had the same tune for 3 years now (~17psi) and it was fine before this started up. I spent some time with Robert and he put in a flat boost curve and it still danced all over so the tune is good. As for the TCV, I am currently using ...

1997 850R - Stumped - Boost Issue
Hello, When I punch the throttle I get an overboost and then it cuts back too far and sometimes will settle on a number and sometimes will keep going back and forth a few times. Typically it will hit 19 or 20 which isn't bad but it cuts back to 13 or 14 which is horrible. It reacts different every t...

Re: What did you do to your Volvo today? (now Sticky!!)
Installed a ScanGauge II. Ran the cable behind all of the panels. Looking good!
