Has there been anything written with any positive results on leaning out the fuel mapping? I hear from Detroit that the GT is set at the factory with a very very rich fuel map. How dangerous, how is it done, is it worth the risk?

I believe John Hennessy is working on one now. I recall someone posting somewhere that JH was doing all the work for free on a friends car to see what the possibilities were.
DBK said:Interesting. That's not as obscenely rich as I've seen on some stock cars, but 12.1 still has alot of wiggle room. Also very interesting as far as the access. Sounds like a major hassle.
