Message	since their first tune designed for 80s fuel. We're 20+ years beyond that now, and our petrol is far from as efficient as it used to be. In fact, Greg commented to me recently that NAs "came from the factory like a bat out of hell" but with around a 12.5 a/f ratio from the factory, they're stunted quite a bit nowadays. He said they do much better running 13.5 a/f, which is a decent bump up. Cheers, JBrobst "A life spent making mistakes is not only more honorable, but more useful than a life spent doing nothing."
