P0266 code After DPF Delete

I have 2012 F350 with about 90k miles on it. I just got the dpf deleted and the truck tuned. On the way home I threw this code. Truck feels fine, but seems to be making a weird sound at idle, and if I give it a little Rev while it's in park the idle gets rough for a few seconds and then goes back to normal. The idle sounds like one of the injectors isn't pumping or something. I haven't driven it more than 30 miles on the new tune but I'm pretty sure the tune I got is botched. I cleared the code for now but this must mean something. Any help would be greatly appreciated. If you need any more info let me know.
