So I was actually going to ask about this next. It sounds like the only way to make sure I am not barraged with engine codes every day and limp mode coming on every five minutes is to get a tune. So then the only issue I have is smell because the smell is as bad as they say it is and it doesn't get better. Will the 200-cell cats actually make that much of a difference in smell? I assume there will still be some stink but will enough be removed that like at a stop inside the car, I don't feel like I'm getting tear-gassed?
