Default Installed intake, charge pipe and bov and now low boost?? - 12-24-2021, 04:39 AM

While getting my oil pan gasket replaced, I had the shop install a CPe charge pipe, a TIAL Q bov, and BMS DCI's.

Now I only push 2.2psi. I was on the MHD "stage 1" tune, and reflashed back to stock just to verify and yep, 2.2psi.

Checked the vacuum line from the BOV to the manifold and its tight, every seems installed properly.

Thoughts? Did my boost solenoids finally knock on deaths door?

I did a brief log ( when it was on MHD Stage 1 )https://19216811.cam/ https://1921681001.id/

First thing I'd do is a once over on all the air lines.... from the cones to the charge pipe elbow that goes to the fmic, then I'd start looking at the boost solenoids (I have a collection of them LOL so it's easy to swap in and out if one is bad). Do you have a bigger line to the Tial BOV? I've heard they are especially picky about the vacuum line.

I run the BMS N54 BOV Vacuum Adapter with the Tial BOV and have no issues... except the elbow to the fmic popping off lol

I'd bring it back to the shop, if it was building boost prior to going in & now it's not, I'd assume there is pretty massive leak somewhere.

If you didn't want to go that route, I would first pressure test the system & see what that uncovers.

If nothing is physically leaking, then I would start looking at other variables- solenoids etc.
