Y/W.
I'd agree that it's a politic thing cause recently, shareholders were complaining about supposed lack of emissions control in Ford cars (they prob mean trucks and the explurgion) cause we have the first hybrid suv and the pzev duratec 2.0, the 500 has LEV II status and they praise the stang GT for lower emissions.
Note: I found out that the new Mustang GT has dual VCT. I was like WHAT? And so I wonder how tuners will deal with that, probably the same way or better than us.

Variable Camshaft Timing ââ?¬â?? Power Without Penalty
Variable camshaft timing was a key in the quest to wring more power from the Mustang�s 4.6-liter, three-valve MOD V-8 engine, while simultaneously improving efficiency and reducing emissions. VCT lets allows the valves operate at optimum points in the combustion cycle, tailored to the engine�s speed and load at that instant.


Yeah so we get dinged with a meager 125HP while new VCT actually helps for HP gain!!!

We introduced VCT so no wonder it's such a pain to work with. I'm sure present-day emissions control is HP friendly.
