Default Re: Exhaust cutout and ECM learning curve?

When we used to run cutouts on carbed vehicles we had to jet the secondaries quite a bit richer than optimal for the full exhaust. I'm sure the Tundra's ECM is going to protest the cutouts in regards to the short term fuel trim. It's not uncommon to get an occasional CEL on OBD2 vehicles with cutouts.
