    Stock intake limitations.

    I'm wondering at what point would swapping out the intake be a good investment/HP increase. I'm planning on installing a Pro West TMIC here in the near future so I'm wondering if I should do the intake as well. I currently have the below listed parts and tune, which my tuner estimated my HP to be around 300-310 HP. I'm curious to see what the mass opinion on this matter is.

    Properly tuned for, intakes do seem to add an appreciable amount of power on the 3rd gens.

    Eric from TP says at stage 2 with an AEM you are looking at a 3-5% increase.
