MPG drop after cam install?

Installed a new cam, etc. about a month ago and I've notice a severe drop in MPG. Not just the expected drop, but down to 5 to 8 MPG city. I expected a drop to 15 to 20 city, am I off base here?

I didn't experience any major drop in fuel economy. I would look into the tune that you have, based on what I have read so far it sounds like it could be running really rich.
