Those numbers were from magazine builds. Tested, from what I recall, on one of the happiest dynos in SoCal...
They were for "selling" parts and I believe all of them were from Dulcich. I don't think any of them were "track" tested either. Proof is in the MPH/HP test.
You're right, I don't accept them as i know better!
If you want to use them to distinguish a trend from build to build, OK. I wouldn't take those numbers, especially #9 as anything but a bit happy.
