The tune should not have anything to do with a hardware change that is supposed to make power or not. The purpose of the injen intake or what they lead people to believe is that their intake flows better and cooler than the stock intake. We know this is not the case. Regardless of the tune, you are limited to what the actual intake mod is doing..in this case, getting heat soaked. I love it when companies say "disconnect" or "reset" the ecu in order for a mod to work or show a gain on the dyno. Then again, when it doesnt, they will say "you need to drive it around so the ecu learns." You should never have to tune the ecu to "make" power from a simple bolt on like an intake kit. If its going to make power, it will make it without a tune. So did Injen want everyone to go back to stock before purchasing one of their intakes? The intake does not work. If it does work, I would love to have someone actually explain how it is supposed to make power. Its not getting cooler air than the stock intake so is the flow that much better?

There's a reason why ALL high performance cars, including BMWs, Ferraris, Lambos, and Porsche's all come with a plastic box air intake. If the open air intakes were all that the aftermarket manufacturers claimed to be, why wouldn't they already come with them?

...why dont all cars come with Alpine MP3 players, coilover suspensions, PS-2's, Recaro seats???

Again the intake is really designed to work on an otherwise stock vehicle. The stock ECU parameters can be varied to work with "some" changes in conditions but with multiple changes of engine hardware it will reach a limit of what the software can adapt to. i.e. "limp mode". This has been the case with all the the late model BMWs since they use adaptation, which on a stock vehicle gives better overall performance and economy. And also, again, trying to say that "cooler" pre-turbo air will do ANYTHING for performance is nonsense. Even if you are bringing in 10degree cooler ambient air to the intake track, it will be heated up again by the turbos and lose any effect. A FMIC is one of the only ways to curb the heat soak issue, and even an FMIC will lose its effect if the vehicle is not moving or if the ambient air temp is higher.

How can it not affeect it? If you have a turbo that is 200F, how is it not different if you are sucking in 155F IATs compared to 98F IAT? Again, there is a reason the cars go into limp mode and its NOT because of the extra airflow. Its going into limp because the IATs are too hot. When it reaches a certain point where the eCU cant make adjustments for it, it will go into limp.

I say stick w/ the stock exhaust and save your money.
