Can anyone help me with this. I know i could probably search this thread for hours and find the answer but i don't really have that much time. As far as the injen intake is concerned. It does not require a tune/ off the shelf map to run properly correct? you can just install and go and your ST will still run perfectly? also, how does the intake work with the AP3. do you just use a map that is technically meant for the Cobb intake? Thanks again. Any info is helpful
