    5 Top Rated Questions

    will this disable the afm?

    • The Diablosport inTune i3 Tuner will not disable your Silverados AFM System (Air Fuel Management).

    Helpful (4)

    Does this allow you to adjust the speed at which the AFM kicks in or even allow you to turn it on or off?

    I understand these tuners usually are VIN specific and will only tune one vehicle at a time, but will the code-scanner function work on other vehicles or only on the tuned vehicle?

    • The code reader will work other vehicles as long as that car is a supporting car to the tuner.

    I already own a DS inTune i3 tuner, how do I go about getting a fuel economy tune? I had the tuner for 2015 ram 1500. I now own a 15 Silverado lifted. Looking to improve fuel mileage without changing PCM. I am going to add the cold air intake as well. Other than that don't want to make any drastic changes.

    Will this fit a 2018 5.3L Silverado?

    • Unfortunately this tuner will not work with a 2018 5.3L Silverado.

      Improve performance and horsepower

      With so many choices, it is hard to decide which one to purchase. I was not looking for on-the-fly adjustments, but I did want the ability to data log. This tuner provided me with options that I was looking for at the price point offered here. The same tuner was found elsewhere for $100 or more. I was able to install the ECM and TCM tunes in just a matter of minutes. Installed on the tuner was 5 preset Dyno tested tunes. I am currently testing the Diablo Tune. What I am liking up to this point, the how the vehicle no longer feels like it falls on its face in stop and go traffic. What I liked about this particular brand and model was the support available for the product. You can easily get custom tunes installed from any local dyno tuner for your custom setup. The Sierra/Silverado forums can direct you on the best direction to go. Another feature that I really liked, is you do not have to buy additional tuners to program a different vehicle. As long as Diablosport supports the vehicle you are trying to tune, you can unlock license spots with just a phone call.
