i would check with mike in the computer section but i seriously doubt that the ported t/b and elbow would or will require any computer tuning.
if it is any indication, the 4.6 mustang guys have about 3 or 4 people casting aftermarket elbows that flow much better than stock. the addition of the aftermarket elbow and a larger throttle body on a mustang makes around 10 rwhp. i would guesstimate that a well ported stock elbow and t/b might give 5 rwhp. would be great if the mustang one fit the 4.6 truck but the mustang throttle body is angled 90 degrees from a 4.6 truck so it will not work.
makes you wonder why someone dosent cast an after market elbow for us truck people.

I find that working on my truck and doing something with my hands really gives me something to be proud of especially when somebody else comments on it. When you do something like polish your throttle body it's not something people are going to see, it's just part of the love of your truck. Kinda like a green thumb only it's a black thumb.

BSA, by porting and polishing, you clean up all the ruff edges and sufaces so it matches up better, witch emproves air flow, all the combustion engine really is is a big air pump, the better it sucks in air and expels exaust the more efecient it is witch will help HP and MPG, porting and polishing the throttle body and elbow wont give a huge diffrence but every little bit helps

The stock TB has a lip in front of the butterfly. Using the coarse grit wheel removes this lip and increases the amount of air that can flow into the engine. Granted it is not a lot but add gasket matching and a few other things and it will start to show. I gasket matched my intake manifold and the heads. In certain areas I removed as much as 1/8th of an inch of metal. Can you say, improvement?
