FAQ
Does a ecu tune add horsepower to a Dodge Charger?
A tune can add power when written for your mods and fuel, but advertised peaks are not a promise for your car. Use a reputable tuner.
Is a ecu tune hard to install on a Charger?
Easy flash / pro dyno for custom. Budget about Minutes (OTS) to a dyno day. If you are not set up for DIY work, get a quote from a shop that knows this chassis.
Will this void my warranty?
In the US a modification alone does not void an entire vehicle warranty, but a dealer can deny a claim for a failure they can show the mod caused. Keep stock parts.
Is it CARB legal?
Only if the specific part or calibration has a CARB EO covering your exact vehicle. Otherwise assume it can fail smog in CARB states.
Did you test this exact kit?
Not as a blanket claim for every Charger listing. This verdict is general, generation-aware guidance so you know what to verify before you buy.
