Default No check engine light?

Kind of confused but, in ACC on I have a MIL light, but I just finished installing LT's, catless x pipe, cam, air pump removal, and a wideband. I did a short cam break and spring break in (run at 1500-2000 RPMs till t-stat opens and then some) What im confused about is that there is no MIL light with the cats removed, the secondary o2's gone and no air pump.....? Shouldn't there be at least 3 codes? (2 for O2's and one for air pump performance)

They don't trigger immediately. They will eventually. I pulled my cats and after resetting the codes, it takes a few cycles before they set the light.
