Common questions.
Does the Charger Hellcat tune differ from the Challenger Hellcat?
Same engine, same PCM. Calibration is identical platform-to-platform. The Charger gets the same tune as the Challenger of the same year + variant.
PCM unlock — what does it actually do?
Hellcats ship with a write-locked PCM. We unlock it (one-time, persists for the life of the vehicle) so we can flash custom maps. After unlock, the PCM behaves like any other tunable Dodge ECU.
Will I need a fuel system upgrade?
Stock fuel system is good to ~800 wheel hp on 93. Past that, port-injection or a meth kit is the next step. We spec the path on the call.
How long does the appointment take?
Stage 1 with PCM unlock: 3 hours. Stage 2 with pulley install: full day.
