Developed by Peitz Performance, this Hellcat tune specifically for the Dodge Challenger SRT (2018-2022) will certainly give you the extra power, responsiveness, and feel you are looking for. Since its inception, Peitz Performance has been at the forefront of Hellcat tuning development starting with the Challengers and Chargers and now the TRX, Durango, and Trackhawk. In fact, Peitz Performance was the first to tune the Hellcat as well as set multiple records since then.
What does this mean for you? You are getting the best of the best! Take advantage of the years of research and development with a Hellcat-specific tune available from the Stealth Performance team!
This tune will not only produce more horsepower but will also enhance throttle response and really make the car feel like it should have from the factory! We highly recommend adding the transmission tune as well for improved shift time and feel.
An RTD is a "remote tuning device". Simply put, this device allows us to easily send our tunes over to you. Even more than that, it allows you to data log after our tune is installed to make sure everything is good to go!
A tune, otherwise known as calibration, is a file written to the computer in your vehicle that runs your engine. This control module is sometimes referred to as the Engine Control Module (ECM), Power Control Module (PCM), or Engine Control Unit (ECU).
The tuning process will void the factory warranty related to that modification. For example, if your windows stopped rolling up, this should still be covered since it is not controlled by the ECM.
