Default Cant lean car out after aeromotive boost ref reg install

Earlier this year I upped the boost on my car from 9psi to 11psi. The car then struggled to get to my commanded boost enrich afr of 11.5. So I installed an aeromotive boost ref fuel press reg. And now I cant get the car leaned back out. WOT AFR is stuck between 10.1-10.5

I tried setting the base fuel pressure at 58psi, 56psi, 53psi, 50psi still everytime wot afr is in the low 10s
I even tried changing my boost enrich afr to 12.0 and it still runs like 10.2afr?

Am I missing something?

How is the reg/system plumbed?
Did you change the inj constant to reflect the added boost reference?

Reg is on the fuel rail and uses the stock evap line for return.

School me on what I need to do with this injector constant. Is this in the "injector flow rate vs. manifold press (kpa)" table?

We use Efilive. It is g/sec vs kpa. If your reg is vac referenced, the values are all the same.

Yeah thank you for getting me pointed in the right direction. Looks like I need to change my IFR to the 0kpa value all across the board. As well as my offset table.
