I get 16 city right now with practically no highway driving. I'm curious to see yourm "new" mpg with the cat.
I am with you on this one, I'll keep looking for ya firemouth.
I am getting roughly between 17 and 18 in city for the blackbeauty, engine light every now and then, usually with a slight miss (I am sure it is getting ready to **** another ignition module, last one was changed brand new over 60K miles ago) and I can't seem to drive it anywhere near how a "civilized" human being would. It is fun to hear the supercharger whine.

I get about 16 mpg average, 22 mpg all highway... the Northstar is a guzzler, that'* for sure. :( This is all on regular though, doing a few tanks of that, a few tanks of premium later to see the difference.
