This software was actually used as the "prototype" software for the 2004+ Ford F-150 and 2005+ Ford Mustang. The major difference was that the 3.9 Liter V8 in the Lincoln LS, Ford Thunderbird, and Jaguar S-Type responds very well to induction and exhaust modifications.
Every engine is different. Although psyshack used one in a Honda Accord, there are many factors in place. The first factor is that when one performs a "performance modification" to their vehicle, it generates a tendency to want to utilize said performance modification resulting sometimes in a heavier foot. Other factors can include the ECU programming and its ability to compensate for the additional air intake. Most newer ECU's will compensate for a certain ratio of intake air to maintain the perfect 14:1 Air to fuel ratio. Once too much air is introduced, some older ECU's could not compensate in the proper way resulting in the fuel injection system over-compensating and causing the engine to run rich. This is where psyshack likely saw his issue. Although the heavy foot theory is the oine I am sticking to based on the "by the butt dyno" and "louder at WOT". This would indicate a more aggressive driving style that of course would result in a lower MPG. Now, I will admit if I am wrong and there is a certain level of assumption here so if I am 100% off base, I apologize.

You dont run around at WOT much in a I4, 5AT Accord Sedan and keep a lmpg of 32 mpg.
Takes all I can muster up to over come the wifes awful driving style.
Last oil change I put a OEM filter back in threw the K&N in the box and wrote that off as a $50 dollar waiste of time and gas. Not to mention most of the folks that do uoa's see more silcates in there oil from K&N's and other common aftermarket filters.
Now my Ranger has a cone style filter on it and it helped it alot on the upper reachs of the tach. The 2.5L, I4 in it is a hopeless turd of a motor. I havent driven it enough in the last year to look at MPG on it. I need to get the gas burned in the tank now before it goes bad. The filter has been on the truck for 3 years or so. When it was a daily driver I couldnt tell that the cone helped with MPG one bit. But it would pull a hill better, pass better and haul better. The butt dyno showed good for it.
I think ,, in the long run intake and exhaust mods are going to prove to be near worthless on the hybrid motor and the r18a. These engines where purpuse built for mpg. Esp. the hybrid. The days of a sleeper LX sedan or coupe are over IMO. If you want power and a mod'able engine get a Si. Want good soild mpg with a bit of zing, r18a is your mill. You want the upper reachs of FE its a hybrid.
Looking at my r18a you see a cast in the head exhaust thingy. Its not a manifold or a header. It drops right into a CAT. I sure the hybrid is the same way. Thousands of folks are waiting for the magic bolt on parts to make these engines scream like engines of the past. I wager it isnt going to happen for the r18a like folks want and anything for the hybrid will be custom one offs.
Good luck in your efforts
