So when off throttle (no EB), IG coasting down a hill, is that 18-20mg/stroke still being introduced or does the ECM hold back the fuel in order to get the rpms down since there is no throttle input and minimal engine load?

I've always OOG coasted as much as I can (up until this recent test), granted I pull on flat ground and the only time I see a good descent would be a size-able overpass, tunnel or bridge. Typically only utilizing OOG when loaded.

Just weird that the only thing I've changed in the OOG vs IG coasting. I mean, it's a great problem to have lol, just would like to know what's assisting the MPG.
