injector rail can be purchased by the foot anywhere. search google and you find many options.

high impedence injectors are what stock engines use. there available anywhere and are cheap.

low impedence injectors are more responsive but there are more expensive and require a resistor box to use them to replace stock high impedence injectors.

part numbers? i used the underdog controller(the one without the control buttons on the face of the unit)

I went to the link you gave me and this is the part number I got xa58201. Is that the one you have? If so I can just go to the junk yard and get 2 jeep injectors and that's it or do I need a 3 bar map to? I just want to get it right this time. I wasted money and time with the fmu and mad Btm and fcd. That I have new at the house. Thank you for your time.

that part number is for the first link. i dont have that one. click the second link that says underdog racing development. thats the controller i have.

the map sensors are built into the units. you will run a boost line to them when you install them.

Ok I'll give them a call and see what up. Thank you.
