I personally run the jms bap its totally plug and play and no boost refrence is needed so no cutting of any wires at all ,when I installed it on my stock hellcat pump my pump average was 90 psi I absolutely loved it ,if your fuel pressure is dropping to less then what is commanded then its not right if it commands 80 psi and your dropping to 70or less psi ,im sorry but its not right and your injectors get smaller and the car is under performing ,I now have it attached to my dual pumps gotta love knowing your fuel pressure is on point
