what efi parts are these and can i use them on my 360 magnum

I have seen over 500HP normally asperated with Jtec controller, you just have to have correct flash.

yup, you probably right! I dont know so much about flashing them! it may be as easy as any other... I just believe there is much easier when starting from scratch to use a megasquirt,haltech,vems or other like that you may tune all parameters easy with your own laptop, and you also have extra outputs to control turbo boost, fan, fuel pumps etc
