well the hoodscoop wont do anything towards HP numbers. Will improve cooling. But with the STI TMIC I think +15ish

has your car already been tuned, or are you running the OTS mapping? I would personally get a bigger TMIC than the STi, but that's just me. I say sell that STi and get a helix or something else used.

so is your question how much power will you gain from the STi TMIC over the stock TMIC? if so A: not very much. 5-10WHP would be my quess.
and with IC's, bigger is NOT always better, it doesn't work that way. |

From what I've heard sti intercooler doesn't really do much over the stock. I've heard it's really not even worth it. What you should have done was save another 100-200 bucks and went with a bigger tmic and gone to stage 4, you already have the supporting mods. I gained about 30 whp just by having my utec dyno tuned by pdxtuning, rather then using base maps. So instead of buying the sti tmic you should have just had the car pro tuned. IMO.
Keep us updated on the #'s you come up with after the tuning. Good luck man |
