I have a very general question about any Gen 3 or 4 GM engine that is totally stock. Mostly in my shop I see Chevy Silverado pickups.
When the customer installs a cold air intake like a K&N which comes with the filter and the intake duct, does the vehicle require MAF tuning to make the PCM read the new airflow correctly?
I am new to tuning and was reading about "MAF tuning" in the GM Beginners tuning book and was wondering if this would apply when someone modifies their air filter and intake duct like I see all the time on otherwise stock engines.
