14mm Exergy CP3 surging ??

I have a 2012 with a D&J 6.7 and exergy 14mm race series CP3 at Firepunk in which they are working on issues with surging . It ran well with duals.

Anyone else dealt with surging issues with the exergy 14mm ?

How did you resolve ?

Did you have it retuned going from dual pumps to the single 14mm? It needs to be

I assume it was retuned when the 14mm was installed and ran good for that day .
Truck was then trailered to Missouri and started surging when taken off trailer . This is per previous owner . At this time it had 100% over injectors.

It then went back to fire punk , had new exergy 250% injectors installed and I purchased it from the PO. So the exergy 14mm pump is basically still new too .

Lavon is going to try to adjust the pressure from the fass 220 lift pump to help with surge while tuning the truck.
I think he has already tried changing the FCA on the pump.
Also, it is the race series pump.

I am sure he will figure it out , just wanted to know if others had similar issues and what it took to fix it. I thought I have read on here before where someone had surging issues with the 14mm , however I can't find the post.
