5. Range Technology Active Fuel Management Disable Device

Range Technology Active Fuel Management Disable Device

Other than this one, there is no other tuner like it. Its sole purpose is to turn off the active fuel management system in the 5.3-liter V8 engine of the 2007-2018 Chevrolet Silverado.

What’s the big deal?

Vortec 4th generation engines have a severe problem with the active fuel management system that has been mentioned before.

By turning it off, you’re forcing the engine to use all eight cylinders instead of only four, which should fix the dependability problem..

Range Technology’s active fuel management disable device is the simplest of all tuners to install. The OBDII port is all that’s needed to get it working. If you’re looking for more features but also the ability to disable the AFM, there are alternative solutions in the market that cost less than $220.

Diablosport Trinity 2 EX Platinum Edition Performance Programmer

There’s little doubt that the Diablosport Trinity 2 is the greatest tuner out there. It offers one of the most comprehensive feature lists, as it is compatible with all 1999-2018 Chevrolet Silverado vehicles.

The following is a list of the features that can be found on the

The Diablosport Trinity 2’s price is the sole reason for its poor ranking. If you’re going for a performance setup, spending $750 on a tuner isn’t ridiculous, but for an average Chevy truck owner seeking for a performance bump, I believe it’s too pricey.

8. Edge Products CTS3 Insight Monitor

How To Pick The Right 5.3 Silverado Programmer

The right programmer depends on your goals and budget while making this decision. Here, we’ll go through the most important things to keep in mind when shopping for a performance programmer.

Ease of Use

Programmers of vehicle performance are well-known for their unintuitive user interfaces, antiquated software, and update issues.

Prioritize upgrades because many tuners have been designed in the same way for years and rely on online connectivity to support newer automobiles. Some tuners can be updated through Wi-Fi, which is more handy than having to plug it into a computer, so check out some user reviews to see what others have to say.

Secondly, the display and controls are covered in this section. In terms of functionality, the touchscreen technology utilized in tuners is on par with that seen on an older navigation system.

A real-time monitoring system built into these tuners may be a better value if you don’t mind paying a bit extra, as you can mount the tuner on your windshield and use it as a heads-up display.


Before making a purchase decision on a programmer, make sure you know exactly what you need because the number of options available varies greatly. Some programmers specialize in a single area, while others offer a wide range of services, including real-time monitoring and the ability to adjust dozens of different systems at once.

However, having more does not automatically mean that you should. For the best programmers, you don’t need all of the bells and whistles since they know how to play the music precisely.

Before you buy a tuner, keep the following things in mind:

You can narrow down your search for a 5. 3 Silverado tuner by answering the questions above!

AFM Control

Because of its importance, I’ve devoted a whole section to the Active Fuel Management system shut-off feature. While many Chevy truck drivers have no issues, the AFM has been the source of many complaints from owners. A good reason Range Technology Active Fuel Management Disable Device is one of the most popular programmers available now.

Tuners that have the ability to disable the AFM system and force the engine to run on all eight cylinders at all times should be considered if you’re experiencing problems with the AFM system or just want to be on the safe side.


How do I get more power out of my 5.3 Silverado?

Installing a cold air intake, throttle body spacers, intercooler, or even a supercharger or a turbocharger is the best way to get the most out of your vehicle’s powertrain.

The throttle response can be improved and a tiny objective improvement in performance can be created, but the subjective difference is far more obvious even with a simple programmer.

What tuner adds the most horsepower?

But Diablosport says that its Trinity 2 EX Platinum tuner can provide the highest horsepower. The Bully Dog GT Platinum tuner is a second choice to think about, as it, too, provides a significant improvement on paper.


The Hypertech 3000 Max Energy Spectrum Power Programmer is our top 5. 3 Silverado tuner because it has so many functions, an easy-to-use display, and so much more all in one reasonable package.
