Custom files for the Chrysler 300C built in WinOLS from your own read — not a generic file pulled from a database. Send the read from your tool and Josh builds the calibration for your exact software version, usually back within 10–20 minutes during file-service hours (9am–9pm Mon–Sat AEST), and supports it afterwards. Typical Stage 1 figures are shown per engine below and confirmed per calibration.

Chrysler 300C FAQ
Do you have a tune file for the Chrysler 300C?
Yes — for every engine and ECU listed above. Files are built from your own read in WinOLS for your exact software version, not supplied from a generic database.
How do I get a Chrysler 300C file?
WhatsApp the read to 0466 659 997 with the engine, ECU, your tool and what you want, or upload it at tacfiles.com for an automated return where a matching project exists.
What gains will a Chrysler 300C Stage 1 give?
Typical Stage 1 figures are shown on each engine card above — measured on our dyno where marked, otherwise the typical gain for that engine class. Final numbers depend on the calibration and hardware, so we confirm per file. Reliability comes first — files stay inside what the engine, injectors and cooling handle comfortably.
Send your Chrysler 300C read
WhatsApp 0466 659 997 with the engine, ECU, your tool and what you want. Hand-built files typically return in 10–20 minutes during file-service hours (9am–9pm Mon–Sat AEST).
Vehicle, ECU and read-method data compiled from the published compatibility lists of the flashing tools we work with (files are returned for Autotuner, KESS3, Flex, DFOX, PCMflash, bFlash, BitBox and more). Stock figures are manufacturer-published values as listed by those tools and may vary by market. All tuning files are intended for off-road, motorsport, agricultural or commercial use only; it is the responsibility of the vehicle owner to ensure compliance with local regulations.
