I read an article about a dyno in california on an Evo when they first came out. They were dissapointed in the results they saw (with 91 octane). They came back a few days later with 93 octane and got much better HP on the same car, with the same stock programming.

It is already approved for MY 2007 and newer cars. The study is still underway for a waiver for MY 2001-2005 cars. The EPA says they're going to try to come up with new labeling requirements. We went through the same thing a while ago with the introduction ultra-low-sulphur diesel for our truck. We and it survived.
