I think Adams somewhere has a post where you'd need to repin the lift sensor connector.
I picked up a spare engine that came with injectors part of the reason being when I get them swapped/calibrated (or self calibrate if I can get the 2 stage kit) I can still use the car as it's my daily.
Stock Akn pump with ake pump head seems to be quite nice working combo. Ake pumps itself are duration limited on pump ecu and thats a shame since seems they are capable producing nice power. Therefore older akn pump with less restricted duration is able to push more. 400hp i think is not impossible to break. And ake is smallest of three plunger pumps, 3x6mm plunger and biggest i've seen from cummins are 7.5mm.
