The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

Stock L67, I am only seeing 2.3 max psi. Also noticing that the BBV stays closed at idle. Anyone have any thoughts?

No vacuum leaks either...

Unplug the electrical connector at the BBS, Let the vac line(from bbv to bbs) see atmosphere. If you get full boost back, it's your solenoid.
I just had this exact same issue.

See post #7 in the following thread...
