Custom tuning allows you to get the exact power and control you want from your truck. It depends on whether you want to race your vehicle, use it for towing, or going on off-road adventures. Each situation needs a different combination of your engine and vehicle components.
By custom tuning, you can recalibrate the speedometer, change your speed limits, RPM and more. Basically, you change the factory settings and tune the engine to suit your driving needs. For example, you can turn your vehicle to a fast car by tuning to get more power and speed.
