Drew - I may be worng but I think the reason that Dinan suggest you get the two together is because Dinan's software is made to take full advantage of the Dinan intake, whereas another ECU programing product may not taek full advantage of it. It could also be a marketing gimmick. As for getting the other two at the same time - it wouldn't hurt. You could always reprogram after the fact, or if you get the software first you could re-reprogram after installing the intake.
It's also my understanding that the ECU will adjust, over time, to the increased amount of air entering the engine without upgrading ECU (considering it SHOULD adjust fuel mixture in proportion to air intake. Therfore greater air intake would dictate different fuel amount to mix. Again I could be wrong, and disapointed if I am. Not about being wrong, but about it not adjusting. But I dogress)). This is not to say that the ECU will take full advantage of ANY intake without being reprogrammed. It (ECU) also will not raise the limiter unless reprogrammed.
*I have to wonder if pulling the ECU fuse for 10 seconds then replacing and starting the engine would cause it re-map the air/fuel mix with the added air coming through the intake*
As far as the auto knowing to take advantage of the new limiter - I have no idea. I would suspect so, as the ECU dictates all that jazz, but can't say for sure.
