Car not doing what its told?

Car is a Supercharged 2014 camaro

I am having a bit of difficulty understanding how much I am supposed to adjust the VE table in order to see the change I'm looking for. For example if I see that the LTFT is adding 10% fuel and I add 10% fuel to that area, i dont see any change to the LTFT in response after flashing and doing another log. Additionally I have noticed that under WOT my fuel pressure commanded goes down from 65PSI to 50PSI even though all the parameters in the tune are set to 65. AFRs show about 12:1 under WOT and about 14.7 while cruising. but i just cant get Fuel Trim to 0 instead of 12-30%.

TLDR: im not sure that the tables i am changing are actually doing anything to the car.

If anyone would like to see a log showing what i am talking about, please let me know what channels you would like to be recorded so that i dont miss anything. TIA

Can't really help, especially as I don't know that vehicle, but...

I'm a little puzzled by the "commanded" comment with the fuel pressure - are you confusing a FP reference entry with the desired value, or does the ECU actually have a mechanism to directly regulate the FP? Normally the FP has a base value set directly by the regulator, which is altered by referencing it directly to manifold vacuum/pressure.

If it, the regulator, is actually set to 65 PSI at the fuel rails, and it drops to 50 PSI under load, it's a strong indication the fuel supply isn't up to the task of supplying the volume of fuel required while holding pressure - some review of it may be worth your time, as otherwise you're applying band-aids rather than a cure.

The pump is PWM controlled, by the stock FSCM. In my datalog i can see the commanded pressure as well as actual pressure. My pump is an in tank a1000 and I'm only seeing about 50% DC from the injectors, which leads me to believe that the pump isn't falling behind. Ill log what I'm referring to and attach it in a bit here.
