I'd consider it very improbable. If he's interested in doing that, he's got more of a chance of finding someone to do it here in the states. 2013 is new compared to most of our buses, but it's still 8 years old. I'm sure someone has a delete tune for it.
The hard part of a delete isn't the hardware, but software. Anybody can go in with a sawzall and straight pipe the thing. It takes the software to eliminate the monitors and keep the engine running after you do so.
In the old days, a person could swap in a calibration from another continent that didn't have epa mandates, and that would allow you to eliminate the devices. They also had the ability to spoof sensor values and fooling the computer into thinking everything was hokey dokey. Some of the very early ones had a check box that you could select and deselect for compliance.
A lot of your recent engines have the emissions monitoring hardwired into the core calibration, making it impossible to remove the software, requiring an entirely new calibration to be created and installed. The guys who are capable of doing that kind of programming like to remain as anonymous as possible, because they have a big target on their back, and it's not just from the epa. Many people can connect to the bus and download a new file. I'm talking about the guys that actually write the file.
