Yo troops so I just fitted compound twin turbos to my gen 2 2500 24v Cummins and need advice on fuel issue it runs smooth on idle and nice at 45% 60% throttle but if I go over that and back off the throttle it just stalls out and won’t start I have to bleed the injector and it starts right up I know it’s a fuel pressure issue but need advice on so I just need fuel lift pum or upgraded high pressure pump or both
Thanks troops

How quickly are you letting off the throttle? Quickly letting off the throttle from max (throttle chop) has been known to lock the injectors. I haven't experienced it but have heard of it happening. Requiring the injectors to be bled in order to get it running again.
What is your lift pump setup and fuel pressure?
