Without a tune you'll run very lean, because the cars are programmed from the factory to be lean already, and you just added more air. It will work fine but if you want to get the full potential of your intake, get the tune.

I was getting the occasional lean code on startup before getting tuned when my only mod was the Stillen Gen 3 w/o a tune, but it would only seem to happen on cold mornings and it would clear up immediately.

Haven't gotten any codes since getting tuned though.
