It is $50 for the service from the guy. If it works out and I like the work, then I will send him another to be taken to max bore. They replace the butterfly and smooth the screws.
Village does it, redline, maxbore, etc. A search will lead you all over. This guy works with Saturn stuff, and this tb is off a twin cam.
I feel kind of stupid hopping up a saturn, but if it helps it might be worth it. You add a turbocharger and you never know.
