Amazingly enough, you'd get some fuel economy back by going to 606 plugs, and a 195 t-stat. If I had one of these again, that's what I'd run with the fans set to I at 205 and II at 215.

Also you might be running into the cat test issue. Is your rear O2 sensor connected?

I have this addiction the Wha- Whiiiiiiiiiiine noise at full throttle. If it breaks it breaks, that's what spare parts and maintenance is for right? I drive 80% city too, light to light playing, making Rustangs and Civics mad, making Vettes and Maros wonder what I'm thinking, IDGAF.

19mpg on the DIC, about 15 just city by my calculations.
I was about to say, no way you'd get 19 driving like that.

15, yes.
