As you have seen, we have reviewed tuners from the top brands. As you do your research online, you will come across these brands and others. Since their tuners are unique, their prices are also different. Make sure you order an item you can comfortably afford. Prices can also vary based on if you need a diesel or gas tuner. If you need a programmer with many adjustable settings and good reviews, you will pay more money for it. However, it will be worth every dollar spent on it.
