Is this Wagner IC basically plug-and-play? Meaning: will the ECU/DDE basically just adjust what it does to accommodate the different air flow and temperature characteristics, hopefully all accruing to improved performance and maybe even better MPG as a side benefit?

And may one assume that you will get a bigger marginal percentage positive effect if you start with a tuned machine than you will if start with a non-tuned machine? I guess that's a tough one to answer without seeing the numbers that we have all been wondering about.
It is pretty much plug and play. No doubt if the unit does what it's supposed to do, the car will run more efficiently. Best way would be to adapt the tune to the new IC in order to take full advantage of it.
