Before using device, read and understand the user manual, including 
these additional safety instructions.  Failure to do so could result in 
DEATH or SERIOUS INJURY.
•  Do not exceed legal speed limits on public roadways. Violating trac laws is 
dangerous and could result in injury or vehicle damage or both.
•  Use any enhanced speed capabilities of this product only in closed circuit, legally 
sanctioned racing environments expressly for this purpose. Violating trac laws is 
dangerous and could result in injury or vehicle damage or both. 
•  Do not operate the device while driving. Distracted driving could result in trac 
accidents, death or serious injury, and/or damage to your vehicle.
•  Always perform all adjustments or changes while stopped. Changing a setting while 
driving can interfere with your attention to roadway conditions and could result in 
injury or vehicle damage or both.
•  Do not stack products. “Stacking” performance-enhancing devices or other 
improper installation can cause power train failure on the road. Other products may 
have features incompatible with your device. Follow all installation and operating 
instructions.
•  Some modications may aect other parts of your vehicle. For example, if you 
remove/adjust the speed limiter in your vehicle, be sure your tires and other 
components are rated for the increased speeds they will have to withstand.  Not 
doing so can lead to loss of vehicle control. Modify the speed limiter only for use 
in closed circuit, legally sanctioned racing environments, not for use on public 
roadways.
