well i know for a fact you can run a car without a IAB and a EGR valve in the car..i ran in both my hatch and my notch blockoff plates that i made a work many years ago(should of patent them cuz now i see them being sold!) now its wire 361(red 14-16 ga) that goes to pin 57 on the computer but splits b4 it goes to all the sensors in a parrael fasion as oposed to pulling one sensor out and having them all go out in a series setup

pkrwd is right about all engine sensors are sent out 5v and are sent back less than that witch tells the compter what is going on as all on/off stuff(injectors,coil etc) are sent constant 12v power and computer pulses the neg

now reason behind me ridding the IAB is so i could set my idle and computer would not mess with it(had troubles on botch cars) and reason ridding EGR was just caouz it wasnt used) and yes both cars ran great..one went 12's on street tires with stock tb,intake,mass air,injectors and the same car went 11.7's on a lil dry hit
