Dodge isn’t subtle. It never has been. It’s American muscle in its purest, loudest, most unapologetic form – and the HEMI engines at the heart of these beasts are a masterclass in mechanical intimidation. At Auto Upgrades, we take that raw brutality and refine it with precise calibration work that turns chaos into controlled devastation. Whether you’re running a Hellcat, a Demon, a Scat Pack, or a RAM with a hardworking HEMI, we take what Dodge already made outrageous and dial it into something genuinely unhinged.

From the supercharged 6.2-litre HEMI monsters – the Hellcat and Demon platforms – to the naturally aspirated 5.7 and 6.4 HEMIs, these engines respond ferociously to proper ECU calibration. The supercharged ones, especially, behave like caged animals once the torque control strategies, airflow models, and boost references are corrected. We’re talking power levels where dragstrip prep goes from optional to mandatory. Spray glue, warm tyres, pray to whichever deity you prefer – because once a calibrated blower HEMI hooks, it hits with violence.

Dodge builds icons. Charger. Challenger. Hellcat. Demon. RAM HEMI. These aren’t cars – they’re declarations of intent.

Unleash the Power of Your Dodge

For Dodge owners, performance tuning isn’t about adding “a bit more power.” It’s about rewriting what the vehicle is capable of. Whether you want mind-bending acceleration from your Hellcat, full-blooded thrust from your 6.4 Scat Pack, or massive real-world pulling power from your RAM HEMI, we deliver calibration work that transforms the entire experience.
