Your tuner likely recommended our Speed Density harness because you have a larger turbo or at least make more power than stock. Often this scenario creates a situation where the stock MAF (airflow sensor) is less accurate. Switching to Speed Density will help the tuner get a more precise calculation of how much air is getting into your engine. We have a great in-depth post on iWire University to explain Speed Density and how it works.\u003c\/section\u003e\n\u003csection class=\"_2RbVQ\" data-hook=\"description-wrapper\"\u003e\u003c\/section\u003e\n\u003csection class=\"_2RbVQ\" data-hook=\"description-wrapper\"\u003e\u003c\/section\u003e\n\u003csection class=\"_2RbVQ\" data-hook=\"description-wrapper\"\u003e\u003cbr\u003e\u003cstrong\u003eWhy Do I Need this Wiring Kit Instead of the Pigtail Included With My Sensor?\u003c\/strong\u003e\u003c\/section\u003e\n\u003csection class=\"_2RbVQ\" data-hook=\"description-wrapper\"\u003e\n\u003cul\u003e\n\u003cli\u003eTo wire the sensor correctly, you need the wiring diagrams for your car year and model to determine the pinout.
