Why not just port/polish the stocker...along with doing the bump stop and epoxy mod. You'll save a few hundo at least...check out http://s2performance.net/ ....Shaner does really great work.:yup:

I don't see no stinkin sig. :lol:

More air, more power. I noticed a difference when I had my stock TB ported and polished. Not seat of the pants, but the computer was having to re-learn the airflow.
