Driving home today my CEL came on, so I got my tuner out and it showed P1000 and P0420 (both for no cats, right?) and I saw an option on my SCT XCAL 2 that said "clear DTC codes" what would happen if I do that? Will it turn my CEL off?

yes, but they'll come back on since its says no cats
p1000 is system readiness
you might need mil eliminators or a tune to turn off your rear o2's

he needs a custom tune, new tuners had that option taken out of them when there new or update the software

Just to throw it out there for whoever has the same problem. There is no harm in running the car with check engine lights on from no cats/rear o2 sensor faults. That is completely for emissions to let you know when your cats go bad and wont hurt anything to drive the car with them on as long as you don't have any other codes show up (that you wont know about because the light is already on for the rear o2s)
