Hiding p codes does only that. Runner flaps when deleted need a lot of fine tuning in cold start tables at the very least. Not to mention you just tottally changed the inlet path of the incoming air. End result will be weak feeling mid throttle without retuning. Really no advantage deleting them with stock intake manifold and turbo. With large(gt30 or larger) turbo and a custom sri thwn yes runner flaps will need to be deleted
So tuning aside because i can work with that.
My real question is why should i not just "hide the p codes" in this situation. is there a reason to fully learn the system and disable the components, monitoring, and any release CWD words that go with it? or is that a waste of my time. I do not want this thread to be about intake flaps, i just want to make sure i understand systems that are not related to emissions and how i "should" be going about coding them out / Benefits to either.
