        5 2015 EcoBoost - Mud

        Yes please

        Love it. Turbo is smoother and holds boost nicely. I already had a tuner with a tune waiting for be used so I can’t speak to deciding if it’s worth the cost of tuning the car since I was doing so anyways.

        5 2019 EcoBoost - EzraFigueroa

        Great Mod!

        Wakes up car and helps hold more boost. it really shines with a custom tune. don't recommend using it with stock tune.

        4 2017 EcoBoost - MiguelA

        Achieves it's purpose

        Boost is much smoother and holds longer. I can tell acceleration is faster. Was not happy about the confusion: TUNE or NO TUNE. I was told (during a span of 2 weeks waiting on a tune request for this part) by several Bama/AM Tuning and AmericanMuscle that a tune IS NOT required for the 2015 EcoBoost and my tune request was declined. Details like this need to be specified...
