Factors To Consider Before Buying A Tuner For The 6.0 Vortec


Each tuner is unique in the sense that they react differently when used on different engines.

While some tuners are very effective to increase speed and torque they might not be a very good choice for larger engines that do not require excess speed.

Understanding what you want from your tuner is an integral part of buying a tuner.

Amongst our products, Edge Products 85450 is best suited for this.

Price Of Product

Tuners are not cheap, some cost more than 700 dollars, and to spend that much money you need to ensure your tuner is worth the money you spent on it.

One way to do that is to check its features and cross-check whether that particular tuner is compatible with the engine you have.

Amongst our products, Innovative Performance Programmer has the best price.

Driving Conditions

Another critical factor is the conditions in which you plan on using the tuner.

You wouldn’t want to use a recommended tuner for extreme torque and speed in a city because that would render the tuner practically useless.

That’s why you need to buy a tuner that suits your driving conditions and will complement your vehicle.

Amongst our products, Bully Dog 40417 is the best for this.
