Performance Numbers for the QSB5.9
These numbers are not exact by any means, my buddy and I went out one nice night and over a few beers jotted these numbers down. One thing thats kind of cool about the new engines is they give you what they call a "SmartCraft" display. Basically it replaces all the gauges you used to have with a small display that shows more stuff than you will ever need. One real nice feature though is it gives the fuel consumption, so you don't need any real time to figure that out, it just diplays it right away when you change throttle.
Without further ado.
