I have a bpu engine with no boost controller. Sometimes the first turbo produces low boost 7 psi and sometimes it goes right to 16 psi. What gives?

If you are seeing 16psi with just the #1 turbo, I would like to inform you that it is going to die later on next week.

i remember having a similar problem to that. Took me forever to figure it out, but it turns out who ever had the car before had the vacuum lines going to the vsv hooked up wrong. I printed out the vacuum diagram off somewhere on the forum and re did the lines and everything worked perfect.
