Actually, I think lance is right, if you think about it, when you downshift the injectors don't have to pump gas to hold an idle speed like they would in neutral.</td></tr></table><span id='postcolor'>
Not if you rev match.  Going into neutral, all you have to do is allow the flywheel to slow down - w/ downshifting, you have the driveline forcing rotation of the engine which, I would think, would require gas.

I may have to do some research on this one b/c now I am really curious?
