VKAT Bank 1/2 fault code (2728/2729) plus 27EB? What?

Got these codes driving today:

1) 27EB INDEX_219_INJ
2) 2728 Lambda sensor thrust diagnostic VKAT bank 1
3) 2729 Lambda sensor thrust diagnostic VKAT bank 2

I'm running Dinan mufflers, Macht Schnell X-pipe (installed 3,000 miles ago) and ESS engine tune. Car has 38,000 miles. Spark plugs done at 22,000.

I know it's something wrong with O2 sensors but not sure what that first code is. Also why would they both go out at the same time? Does that first code have something to do with my injectors, coils or misfiring?

I cleared the codes (using ESS e-flash) but I've got a 600 mile trip because I am moving tomorrow and am a little worried.

Anyone chime in?

Thanks much.

Ever get to resolving this issue? My ss2 m3 has been facing the same concerns; perhaps this is a color issue?
