Closed-Loop EBC Issues
I have recently been trying to dial in my closed loop EBC with setup mode and am experiencing a baffling problem. Closed loop EBC seems to do absolutely nothing until around 3800RPM. This would make sense with a big turbo but I am running a Precision 4828 which is roughly equivalent to a GT2860RS on a built 1.9L block. Furthermore, I have logs of the turbo spooling MUCH faster (see 2022-05-13_17_modified.msl) previously. It almost feels as though the wastegate is wide open until 3600-3800RPM.
Setup:
Precision 4828, old BEGi cast mani, ARTech 3" divorced flow downpipe, fill 3" exhaust
MSLabs MS3 Basic
Genuine MAC EBC solenoid
What I have tried:

What I have tried:
- Put in a brand new MAC solenoid because the old one had some fraying wires. No change.
- Various changes to duty cycle in setup mode -- changes are clearly apparent above that 3800RPM mark but appear to do nothing below it.
- Confirmed continuity between ECU boost pin and 12v power for the solenoid.
- Shaft play seems minimal on the turbo and intake setup is FM's.
- Turbo is going out :(
- Wastegate needs to be adjusted for some inexplicable reason?
- Some inconspicuous wiring issue is causing the MAC solenoid to work intermittently.
- I am missing some setting here or there that is preventing EBC from kicking on.

It didn't take long, but I may have just found the culprit:
Missing a nut/locker on the downpipe, lower right nut was originally loose, gasket has a hefty leak on top.
Next question is, how do I prevent this? Should I run a copper gasket or no gasket? Are there any locking nuts or loctite-type chemicals I can use to prevent this?
