Gotcha.
Ive been working on heavy machinery and vehicles my whole career. It is just as computer intense as passenger vehicles. As such, I diagnose and troubleshoot lots of computer related issues on these vehicles.
Sometimes, actually lots of times, you get secondary codes that are seemingly unrelated to the symptom, its usually because that system is tied into other systems, like a web. When one value is off, it could throw another value off, and the computer isnt smart enough to know that you purchased a pro style intake. It may take that value change and see it as a potential failure.
Lets say...That hybrid system may only turn on when a certain MAF signal is X-Y-Z....So now its expecting a hybrid signal, and its not getting it, hence the hybrid code.
The first and most logical thing i would absolutely do, is revert it back to stock form to eliminate that part from the equation. I can absolutely see why they are requesting that.
Time is money for a mechanic, he does not want to potentially be chasing a ghost, which is a very real thing.
