As always, HPtuners is right on top of the OEMs, already offering support for 2021 Dodge Challengers and Chargers. With the newest version of VCM Suite Beta, users can tune 3.6L, 5.7L, 6.2L, and 6.4L drivetrains to their right foot’s content. An internet connection is required along with six total credits: two for the powertrain control module (PCM) and four for the transmission control module (TCM).

Every ounce of command is at your fingertips with variable valve timing (VVT), spark, transmission, and torque tables among the variables to peruse. Even the venerable Hellcat can be coaxed to purr a little louder with some carefully-considered changes. The possibilities are endless; all it takes is some serious studying online or a look around their very own forum. The benefit of HPtuners is that it’s a system for both DIY and professionals alike. Whether you’re dyno-bound or just learning in the driveway, the MPVI2 and VCM Suite are the tools for you.

Like any other 2015+ Dodge, Chrysler, Jeep, or Ram, 2021 models will require an “unlock” service for tuning. The good news is that, for a limited time, you can get a FREE Dodge PCM modification service with the purchase of an MPVI2 or six credits. After this one-time service is complete, the user can edit and flash away. Don’t forget that 2018+ models will also require a smart access cable to allow reading and writing functions.
