Nice gains! I am glad to see that Ford left some potential in this motor.
I am always disappointed however that nobody will ever take a stock car, and just tune it with no bolt ons at all. I understand that if they did that and saw nearly as good of gains with just a tune as with a tune and a cai, then they couldn't sell their product as easily, but it still irritates me when a cai is advertised as gaining 22 hp when in fact it may only be gaining 1 or 2, and the tune is doing the rest of the work.
Just once, I want to see a company start with a 2011 GT, put 91/93 octane fuel in it, run it until the PCM is advancing the timing as far as it will go stock, then dyno it for a baseline. THEN, load a new tune, tweaking timing, AF ratio, and cam timing - these are the only things that will gain or lose power in the tune, and the only reason a CAI needs a tune is to adjust the MAF table for the change in MAF housing diameter. So dyno it with just a tweaked tune and compare to the base. NOW, install the CAI and adjust the MAF transfer so it is running the same AF ratio as the last tune with the stock intake, and dyno again. This will tell you what the gains from the free flowing filter and larger intake tube actually are, without the gains from the tune clouding up the issue.
Again, I understand this would be counter-productive for a retail organization, since it would probably show a very low value in the bolt on product versus just tweaking the tune. Then again, it could show the intake is a severe restriction on the stock vehicle and that the bolt on CAI has a huge value. The same goes for other bolt on's like headers, throttle bodies, cams, delete plates, and underdrive pulleys. Knowing what kind of gains you can expect from any of these products once you already have a custom tune would go a long way toward the decision.
As a consumer, I just want to know straight up what the best bang for the buck is.
