I sent this out over 8 hrs ago from a different e-mail address.  
I hope you don't get two

> I don't think you will pass with out cats.

Looking at those numbers it appears that I don't have much
hope of passing without a cat-con.

The cat-con that is on the car right now is empty, so it'll at
least pass a visual test.

I may try raising the e-fan turn-on temp, and take out
some more timing, but I sorta doubt it will work.

I don't want to spend a lot of time messing with it, because I
know I can bolt-up the cat and have it pass.  I was just curious
to see if I could get it to pass without the cat.
