I have a 2017.. added a free flow exhaust, cold air intake and tuned with HyperTech... Huge difference! Very fun to drive. I will say that if you add an exhaust, turning off the AFM is key, otherwise youll get an annoying drone when it hits 4cyl mode. Sounds like shit,,
i have a 17’ TaHoe, already have KN intake system and FM freeflow exhaust. Looking at chips but not sure if they yield the results for extra HP, MPG, etc..
