      Ez-efi or xfi ????

      New to this site and need some guidence i have a ford 445 ci fe motor and have installed a twm stack fuel injection . I have tryed to read as many articles as i can on the fast system was going to use the fast xfi but was wondering if i can make the ez-efi system work . A couple of questions first motor has big cam vacuum signal will be low ( i know i will be using a vacuum pump for brakes ) second everything i read states you need a fuel pressure regulator thats vacuum operated intake was plumbed from twm just manual fuel pressure regulator , last intake is not equipped with iac valve , bottom line i would like to be able to do this myself rather than go with the xfi system and have to try and find someone who is capable of tuning the car . Any info would be greatly appreciated !
