Get the most out of your Hellcat-platform vehicle with HHP Racing In-House Street & Dyno Tuning. Whether your vehicle is stock, lightly modified, or built with serious performance upgrades, our custom tuning service is designed to deliver the power, drivability, and consistency your combination deserves.
At HHP Racing, we do not rely on generic one-size-fits-all calibrations. Every vehicle is tuned based on its exact combination, including model year, supercharger setup, camshaft selection, fuel type, engine combination, boost level, and any additional power adders. This allows us to optimize your tune for real-world street manners, wide-open throttle power, and overall vehicle performance.
Our in-house tuning service is available for 2015-2023 Demon, Challenger Hellcat, Charger Hellcat, Durango SRT Hellcat, TRX, and Trackhawk applications. We tune a wide range of combinations, from basic bolt-on setups to much more serious builds including camshaft upgrades, upgraded superchargers, turbocharger conversions, strokers, nitrous, flex fuel, race gas, and multi-boost calibrations.
A proper custom tune is about more than chasing dyno numbers. It is about making your vehicle run the way it should in every part of the RPM range. That includes improved drivability, smoother power delivery, cleaner operation, better throttle response, and stronger performance under load. For customers with more advanced combinations, custom calibration also plays a major role in helping tie the entire setup together.
With over 20 consecutive years of tuning street and race Gen 3 HEMI vehicles, HHP Racing has built a reputation for helping customers not only unlock more performance, but also solve issues that generic or poorly matched tuning often leaves behind. If your Hellcat-platform vehicle is not performing the way it should, or you want a tune built specifically around your hardware and goals, this is the service for you.
