... I mean, you could make it run, but what kind of tune would it be without knowing the throttle position? 
Would it be hard to tune this type if set-up....
Would it be hard to tune this type if set-up.... Basically an intake set-up like the Viper engine has.
But with our PCM's. Dual TB's.
One TB that serves 4 cylinders. Both sides are totally separate from each other.

If you can configure a way for the IAC valve to work for all 8 cylinders, set up the throttle bodies to open by a cable equally and have one report an accurate TP% angle with the TPS, then it could be done in SD fairly easily. Don't know how you'd set it up with just one MAF signal though if it wasn't an SD tune.
Yea, the setup would be Speed density and wouldnt be that hard to tune at all - as long as the car was actually set up to run that way, then there really isnt a problem. a TPS and an IAC are not required.
Ok, so it must be a SD tune.
It can be used with our current PCM's.
MAF would be removed from the system.
With no IAC or TPS....would it simply be set to idle using the old screw method?
???
What do you think the size of the TB's would have to be for a stock engine.....and then for a 427ci or 454ci?

You'd need a TPS and IAC, or you'd never get it to controll the idle. As far as using 2 IAC, the crossfire intakes used 2 of them, since they had 2 throttlebodies, they were wired in parrelell.

Verdad Gallardo But can the PCM operate 2 TPS sensors?
If 2 IAC's can operate by simply splicing them in series, that problem is solved.
.
I would think if you can make sure they mechanically operate equally (i.e. 100% throttle on the left = 100% thorttle on the right), then ideally you only need 1 tps sensor to report back to the PCM.
The crossfire setups had a proceedure to calibrate the 2 throttle bodies to each other and only used a single TPS.
I think you'll need a balance tube between the 2 halves of your intake, to assure they'll both at the same vacuum, otherwise you'll need 2 map sensors
