New CEL code arrived with latest Whipple tune... Ideas?

[Predator]

I installed the latest Whipple file a couple months back and ever since I keep getting this CEL code..





Performance related mods: Whipple tune + Borla S Type Exhaust

It appears to be some sort of emissions related code. I called Whipple and they 'created a ticket' on the issue but I have yet to hear anything back... figured I'd ask around here... any ideas?!

Is there an aftermarket downpipe on the truck?
A P0430 (and P0420) code is normally caused by excess airflow over the cat.
The vehicle is normally comparing the signals between the front and rear o2 sensors in order to determine a cat is installed, functional, and not blown out.

No, I've always run the stock DP. I only have the Whipple tune + Borla S-type catback exhaust.
