The Challenger is already a beast, with enough performance to shame many other so-called muscle cars, and even a few hypercars but who are we kidding? We always want more power, right? The good news is that your Challenger is ready to unleash even more power, once you get down to upgrading the necessary parts and tuning the engine. In the old days, you could simply give it a bigger carb and maybe some open headers. Sure, tuning carburetors was a bit of a ‘black art’ for most of us, but overall, it was quite straightforward. There were no computers or engine sensors to worry about. On the other hand, with the sophisticated power inside your Challenger’s engine management computer, once you have the right tool for the job, releasing some more horsepower and torque is relatively simple. If you’ve upgraded the air intake system, fuel injectors, and exhaust to let your Mopar muscle breathe better, you’ll want one of our Dodge Challenger tuners so you have the means to remap the fueling. Depending on your specific needs, you can program in more top-end power for ultimate speed and better pull through the gears, or you can dial in increased low-down torque to help you get off the line better. With the right Challenger tuners, you should be able to improve performance in both a straight line and at the pump, as well as enjoy smoother running and better tractability. For the weekend warrior, there’s no need to become a NASA scientist, either. With our custom tune products, you get a simple file that you upload to your Challenger using your tuner. Custom tunes are available on a standalone basis or packaged with upgrade parts to make the most of the tune. Our SCT X4 tuners are ideal for flexibility and power when it comes to remaps. To maximize your performance, grab your tuner and head to a dyno today!
