Please dont drive that truck in ohio.
Im not in the business of tearing people down, but please sit back and rethink what your doing.
I have two extra throttle bodies. You are welcome to one if you want. I really would hate to see yours fail and you hurt yourself or possibly my Family or friends on the road.
Now if you were machining one on a CNC that would be cool.
Hot roddding is about innovating and trying to gain speed/power with low cost as possible, but this is not hot rodding IMO.
Good luck.

... A carb never had a IAC and they idle just fine. You set the the idle speed and wala. Choke controlled cold idle but that was it. ... I really still can't see the absence of the IAC causing any issues if the computer will get over it's self.
Someone please go unplug your IAC and see what happens. I would guess they fail open so worse case if it is cold you may have to warm the motor up and it might idle slightly high. ...

So of course the factory doesn't get finished on time, and you have to pay extra because each trade had to train you in their field. You should have just trusted from the beginning that they knew what they were doing, instead of coming in and telling them how it should be done, because you are the type of guy that would tell a tradesman, "Why do electricians charge so much, you just pull wires through pipes. Anybody with the right tools could do that". Or "Why do pipe fitters make so much, you just run pipes from point a to point b, anybody with a threading machine could do that".
So it's the same here. You open the hood of your truck, see something that you don't understand, and remove it because if you don't know how it works, it isn't needed. Then you come here and instead of asking questions, you start telling us how things are, and you tell us your ideas, and you are right because nobody is proving you wrong. Nobody has the energy to start from scratch with you, and when people try, you argue, draining more of our will to help. Don't you understand you are being like a little kid?
A carburetor is an entirely mechanical device based on the principal of the venturi effect. Air goes through the carb, and by venturi action draws fuel through the jets. More air draws more fuel.
Fuel injection is entirely electronic. Opening the throttle and letting more air in does not bring in more fuel, the computer adds more fuel when it measures more air. There is no single instance where the computer is not in control of the fuel.
In a carb, there are all kinds of devices that control the amount of fuel at idle and part throttle. Bleed jets that change the effect of airflow at different throttle settings, slots to change fuel flow with minute throttle adjustments, throttle cutaways, holes, etc.
Fuel injection has injector pulse width, and either IAC or electronic throttle control. The IAC makes constant adjustments to control the engine, and there is a pile of tables to tune in HP Tuners that pertain to idle airflow. 03sierraslt, me, and anybody else with cam that is about the same as yours, who have their own tuning programs, have been through hell trying to adjust these tables to make their vehicles drivable.
So please understand how we feel when you let us know that the most difficult part of making an EFI engine drivable "Isn't all that important".
I hoped opened your eyes, maybe even just a little.

Only recommendation I'll provide...don't remove the front brakes, upgrade them. Get the biggest, baddest rotors and calipers you can find. Because you're going to wish you had them if the throttle ever does get stuck open.
There are two facts/sayings that are pertinent here.
1) "I have not failed. I've just found 10,000 ways that don't work" -Thomas Edison
2) "Don't reinvent the wheel." -everyone on the forum

Well put Mike. Much like you stated, I don't have the energy to get into all the details. Kinda hard to explain the tuning side of it to someone who doesn't tune. Its easy to simplify something into nothing however in the real world "Something" usually is there for a reason. A carb motor and a Fuel injected motor are two complete different animals, for someone to compare them is only going to make them more lost. Like Ive said before, at this point its like beating a dead horse so to speak.
