If your car has a custom tune that was generated on your car while the fuel pressure had the same profile, its even less likely related.

Ahhh.. I REALLY should have asked you before embarking on this lol.
The good news is, I was able to get an assembly from a wrecked Z for cheap so I will just replace the small venturi piece and call it a day... I would experiment with drilling the regulator, but the assembly I picked up is not 100% as the accident the car was in snapped the rods connecting the hat to the bucket... If i was completely functional, I would experiment till the cow's came home since I could just pop in the replacement.
Based on this feedback, it looks like I should just restore the state to the way it was before since I was tuned that way anyway and it is not likely to be the source of my wandering idle. The search continues!
Thanks a lot for your guidance on this phunk! You are the gold standard for vendors around here.
PS - I'll post a FS thread soon to part out the extra assembly. Should save some headache for anyone else that just needs a small piece.
