I received a Stage 1 tune from Active Autowerke (ECU OBD Flash) and I am also going to install an Injen intake at the same time. I mentioned the addition of the intake to the software support at AA and they responded with a message that "The intake shouldn’t affect much other than sound, stock intake isn’t much of a restriction." Their recommendation was to run the Stage 1 tune I had already received. While I don't assume there is power gains to be had and tuned for with the intake, I would think that there might be a slight change to be made. I've read posts mentioning possible rough idles that were solved through a tune update, so this is how I'm coming to that conclusion.

Does anyone have any feedback regarding the possible need for an updated tune file, or am I over-thinking the intake repercussions?

U might get a code but that's about it. Just re flash it if ur concerned. No harm in doing it again

Most idle fluctuations adapt through the regular DME software, not the tune. Other issues with CEL usually come down to leaky MAF's.

You won't need to retune.
