I had a similar situation with my car, however my CEL did finally come on after about a month and a half...

make sure the light proves out when you go to start it maybe its a problem with the bulb, just a thought

Default tunes on some programmers block these codes. You state you are using a Predator--are you using the tune, or just data logging?

Don't sweat it. Your tuner is blocking the codes if you call predator they could give you more info.
