The X4 does not come standard with a mount. A windshield suction cub mount can be purchased separately here. 5-Star can write High-Altitude tunes for your truck, and if you spend most of your time above 3,000ft, 5-Star generally recommends getting a tune tailored for high-altitude use. Give us a call directly at 623-434-5277 so we can get you the correct tuning for your truck.
