You want to see how fucking much of an idiot i am?Thanks, that's what I was hoping to hear

I’ve done that, too. The T-bolt is supposed to go over the rubber thingy.
@TheFixer - I loaded your logs.

@The Fixer’s Logs from 7-Aug-2022
Check out the discussion of The Fixer’s new build this week

A couple of things apparent from your logs:
1) your wgdc tables need adjusting. WGDC (PID) too wild / over correcting after shift at lower rpm. Probably need to reduce your P and D tables somewhat.
2) many 3-4*Timing pulls - I’m not sure why? Adding a few gallons of ethanol or E85 should quiet things down.

I didn't tighten it and came off. Not sure how I missed it.... but I did.I’ve done that, too. The T-bolt is supposed to go over the rubber thingy.
I think I might need to snug the others a little more.
Also need to make sure the BOV is working right.
We are working on getting things dialed in. Those logs are from the first custom base map.
Right now I'm trying to figure out where I'm having issues building boost.
I've probably got to tighten some more fittings. I've also got to make sure the BOV is operating properly. I think I'm losing boost from that. I'm going to put a heavier spring in and see what that does.
Also going to change the o ring where the charge pipe connects to TB. It felt a little loose when I was putting it back on.
All good ideas - best of luck with your build!
Also - I’ve experimented with Tial BOV springs, and the 10 psi one seems to work best for me.
I’ve also experimented with the o-ring for the charge pipe to throttle body connection since mine felt loose, too. But the slightly larger o-rings I tried were too thick and I couldn’t get the charge pipe to fit onto the TB. If you do find a slightly thicker o-ring that seems to provide a better fit please share the size and source.

I was just helping a neighbor kid with his setup and his O ring for the charge pipe does not fit, had to put it on without it. IDK how, or why or what brand the change pipe is but I can tell you it will not fit. Maybe someone makes a smaller one?
Stock is only supposed to hand 8psi or something low. Aftermarket BOV's can handle a lot more.
A BOV controls boost since that is what was in question.
I know the stock valves can handle more but at what limit and for how long? That is why an aftermarket BOV is used in most cases.
A bov doesn’t directly control boost, that’s the job of the wastegate. But yeah the stock valves can’t really handle more than stock boost since it can create a boost leak when going more than 8psi
BOV’s sound cool, they look nice too, shiny, and I don’t have to worry about my stock diverter valves leaking boost.
Still seems I have a boost leak somewhere. Driving me nuts.
I tightened every fitting down tighter from the outlet to the charge pipe.
Based on my manifold vacuum I changed to the heavier blue spring in my Turbosmart bov.
I did a smoke test. Blew into the charge pipe and smoke only emerged from the filters on the inlets. Also smoked it with inlets plugged. No smoke coming out from any where.
I will do a pressure test now using my air compressor. Maybe I'll hear air hissing out of a fitting somewhere.

One of my boost solenoids is operating erratically.
Going to order a set of pierburg solenoids.
Also need to order a longer intercooler hose for the intake side. My clamp seems to be sliding halfway off the hose. Pressure builds and the hose pushes the clamp off.
