Yes even with the short ram you will need a tune. Think of it like this, the ecu controls everything related to air, fuel, boost, and timing. Anything that can potentially change that kind of stuff needs a tune. Now, the cbe does not need to be tuned for. (It's just a sound mod, no HP gains) Nor does a turbo inlet. But a short ram will make changes to the airflow very near the maf so they usually require a tune of some kind. Hope this helps.
