    tuning for K&N intake quick question

    If you just replaced the stock with a custom cold air intake. What's the general idea with tuning to get more out of it?

    do you decrease the Mass airflow vs. freq. table?

    or do you increase the values.

    Generally you would have to increase most values because you are now getting more air in causing the car to run leaner.

    Hi how much increase in MAF Airflow vs. Output Frequency were talking about here to

    not run richer? .005 to .010 lb/min?

    In the absence of a wideband I would adjust your MAF so your LTFTs are back to 0 or slightly negative.
