We don't have a enough data on various rigs yet to really have this OPEN/CLOSED thing characterized yet. If we can get more locals to post up their info, we'll get a better idea of patterns.
I'll bet you see noticeable differences. If nothing else, the little extra oomph is a blessing.
I've only seen one post here or on MUD of NO increase in MPG, and, IIRC, that was only on one particular route.
Do you have a SG? If so, monitor when/how often you're in open loop (at a minimum), before and after the MAF.
