Alright then when I was researching I must have misread. So I'm guessing that the skunk2 throttle body must be measuring the butterfly size as in the smallest area in the throttle body opening. Is there any stock easy to find throttle bodies that would show a little gain on the dyno without hurting the wallet as much as skunk2 would like to do? I know it wouldn't be much but if I can get like 3 whp on the dyno thats 3 more than I had before I put the part on. My goal though is to get a throttle body that is matched with the skunk2 manifold as closely as possible.
