JB4 + BEF only targeting 12 psi

I recently installed a BEF with MHD to go along with my JB4.The first few days were absolutely fantastic. The car pulled hard and seemed to run smoother than it ever has previously. These past 3 days however, I have noticed that my boost gauge on fuel has only been reading around 10-11 PSI max in any map (1,2,5) on the JB4. I spent hours checking for boost leaks to which I found none. I ran a few short logs and have noticed that the target boost from the JB4 is only 12 psi over the whole run. I have boost by gear disabled (set the value to zero) and have the max pressure set to 20 psi. I have had no check engine lights and the only code I can get is a shadow code from MHD that is 2FCA which is related to high pressure fueling. I am not sure if I need to replace my pump to resolve the issue or what is going on. The mods on the car are RB ONEs turbos, VRSF inlets, VRSF chargepipe, and VRSF downpipe. I am running 93 octane from shell. Any advice would be greatly appreciated!

I posted a log in the zip file that I attached. It is a jb4/ .csv file. Should I add screenshots of the graphs too?

No graphs aren't very helpful.

6cyl timing value looks incorrect, maybe needs to be 5 for ije0s? Anyway run map2 on the BEF it's a 17psi target.

Okay, I will change the value to 5. I’ve ran on map 2 before and it would still give me the 11-12 psi issue I am having now. I just decided to upload the map 5 log since they all felt about the same in the car (map 1,2, and 5). I will relog with the new 6cyl value and on map two.

I think that was my issue, car felt faster and Im pretty sure the logs are where they should be at now. Any other comments on the run would be appreciated too. Thank you for your help.

I swear the main reason I don't want to stack a jb4 is the atrocious logs

I don't know, I'd like to help but I can't read that
