Base stock is about the last thing that’s significant here. This supposed test that you “remember reading” is likely contrived or nonexistent.

Another good non-topic topic.

Well no, it certainly exists out there in the information world, whether it was accurate or just a paid test for a sponsor of the medium is anyone's guess. The dyno test existed but I can't say it was real or not.

Yes and my experience it isn't purple in 200 miles!
