Proper Tuning F.A.Q.
What does proper tuning entail then?
When we refer to proper tuning, we are referring to adding enough fuel to compensate for the added airflow. In doing so, this will allow you to eliminate the lean issue and bring your motor back up to having a proper air/fuel mixture.
Why should I properly tune?
When you put an aftermarket higher-flowing exhaust on a vehicle, it throws off the current air/fuel mixture that the vehicle is setup from the factory with.
This is the first time I have bought an aftermarket exhaust, do I need to do or get anything else?
Yes, you need to properly tune your motor.
How do I properly remap?
By using a fuel controller (aka programmer), you can remap and tune your motor.
I have a fuel injected vehicle, what do I need to do?
You need to properly remap your fuel system in order to add fuel to compensate for the added airflow of the new exhaus
Do I have to remap/tune even if I’m just buying a slip on exhaust and not a full system?
Yes. The biggest increase of airflow will come from the less-restrictive aftermarket muffler(s) and not the head pipe(s). Given that, your motor will still run lean and requires proper tuning.
