More than likely, you have one of Ivans custom maps.
It sounds like the previous owner bought the whole package from Ivan, which is a good thing. Ivans kits are great, I can't wait for him to come out with one for the '14 models.
Before I suspected the mapping, or messed with it, I would look at the obvious.
Intake and exhaust gaskets, can and will leak through time, and will effect the fueling.
also, the air filter, is it clean? check it, check the air box. I'm not sure, but I believe there were some block off plates that needed to be installed for that kit. did they fall off, are they loose? I also think there was an exhaust valve that was bypassed or something, this may have come loose, or something.
I understand Ivan is a very down to earth guy. You may try calling him, or emailing him, and explain your problem. He may know exactly what you should look for and point you in the right direction.
Like I said, it sounds like you have the complete kit direct from Ivan
here is a link to the kit:
