Reply To: Cat delete, adjust fueling?


My de-cat arrives today. I have to imagine it flows more air than stock, but who knows. I may wait to put it on until I can get a power commander. Flowing more air is not bad in and of itself, you just need to flow more fuel to match, it only causes problems if the fuel injection can’t make itself rich enough to keep up with the increased air flow. The horsepower gains aren’t going to ruin your motor as long as the fuel mixture is right.
