Back to the V6 section for you. No soup either.

That's true....for the V6. The V8's don't have dual-length runners, so there's not benefit to the butterflies.
Screw wiring them open, just remove them completely. I took the plates out, then removed the entire secondary plate shaft and RTV'd the holes closed.
If you don't tune it, you might notice a slightly rough idle when it's cold out. No ill effects otherwise.

Let me post a bit more information.
I have wired them open before when a code came up about "intake runner closed". The car seemed quicker by the SOTP.
The car began to not start and miss after probably 10 heat cycles if I were to guess. I was not there when this occured but that is what a mechanic told me. He told me it was because the butterflies were wired open.
He said when he closed it back (cut the wires) that it stopped.
Since he has did that, the car felt slower.
I am very familiar with performance of cars and the feel of something that might effect power. I felt this.
I have modified my own mustangs and others. I'm just posting that so you don't think I was 'illusioned' by the want to have more power.
The swivel in the IRMC box was cracked and allowed some slack in the line. I figured this caused the valve not to open up all the way - that is until I wired it open and 'felt' a gain.

think of it like they they open when the engine needs the more air. so way would you open them at idle and cram the engine with more air and to me that seems like it would run lean at idle witch isn't good.
The engine will only take in as much air it needs at idle. The secondary plates on the V8 are only a restriction with no hp or torque improvemnet properties.
You do have to adjust the timing and fuel below the normal opening rpms though. Basically below 3300 rpm the V8 is neutered from the factory.

Paul (SHOZ123) is correct about this and it would be good if those posting inaccurate information would desist in doing so. This question has been settled for a couple of years and we should not be leading new owners astray on it. Wiring open the secondaries on the V8 Gen III SHO has no serious negative effect, and if you are not subject to very cold weather starting, no negative effect at all.
