I just installed CPR fuel rails on my 5.7 supercharged challenger,and the pressure is around 54-60 psi. Should I change the fuel pump for more pressure?? Do I have to change the injectors too?? Running only 6lb of boost. Thanks

I went for a slightly used 6.4 fuel pump when i had my S.C. installed, its not as good as an Arrington fuel pump but its cheaper and better than the stock 5.7 pump and it seems to be fine with 8 lbs boost. Also the Magnuson S.C. came with upgraded injectors.
