Best Tuner & Programmer for 6.0 Vortec

The 6.0 Vortec is a heavy-duty engine produced by GM and was used in several Chevrolet and GMC trucks to achieve as much as 300 to 350 horsepower. It’s been a popular engine known for its power and towing ability.

Although your vehicle already has power-packed features, using a tuner on your truck will give you back the power that could be fading after years of usage. Each truck has a specific calibration set by the manufacturer to give you a targeted output, whether for towing, speed, or fuel mileage. If your truck is not appropriately programmed based on how you use it on a daily basis, it may not give you the performance you actually need. We’ve chosen the best tuners for 6.0 Vortec engines that will help you regain or surpass that performance your truck used to have.

A Tuner, Monitor, and Performance Tester

The Edge CTS2 Evolution Programmer’s latest interface has a sensitive touch screen. For better contrast, or if you want to match your screen to your interior, you can change the background color. It also has an ambient light sensor which will automatically adjust the brightness of the screen.

The device comes with 5 pre-loaded tunes labeled in levels to help you figure out which one will give you the performance you want. The well-structured levels are also tied to specific usages to help you decide which one is best based on how you use your truck on a daily basis.

  • Level 1 – Trans Only: Provides firmer shifts for longer transmission life.
  • Level 2 – Economy: The lowest power level specifically tuned to increase your fuel consumption.
  • Level 3 – Towing: Typically used to give you the necessary “pull-power” if you need to tow heavy loads.
  • Level 4 – Performance: The fuel injection and timing are semi-aggressively calibrated to achieve an anticipated power gain.
  • Level 5 – Extreme: The highest power level that aggressively calibrates the fuel injection and timing for fuel efficiency and maximum power.

If you want to add more power on top of these levels, you can always make adjustments to help you achieve the type of performance you want for your truck. You can change the tire size, gear ratio, speed limiter, and more.

The Edge CTS2 Evolution Programmer also works as a monitor through its multiple gauge screen setup to help you check your truck’s performance.  You can dictate the screen layout and choose which parameters you’d like to see. This includes the electronically controlled transmission, revolutions per minute, miles per hour, and more. Apart from these, you can also record data logs of how your truck is performing within a specific condition such as when you have to drive over rocky terrains or steep inclines. There’s also live monitoring to ensure that everything under the hood is not overheating nor under too much pressure.

It can also help you see the performance gains in your truck through its Performance Tests. You can run them before, to set a baseline, and run them again after you tune to see the improvements.  This will help you figure out if you want to move up to the next level or not.

Why should you buy it?
