Pre-Written Tune Files

2009–2012 RAM HEMI 5.7L / 6.4L Tune Files

Built specifically for 2009–2012 RAM trucks running the 5.7L or 6.4L HEMI using real-world dyno data, street testing, and proven Mopar calibration strategies. Whether your truck is stock or running an aftermarket cam, each file is dialed in for clean idle, smooth drivability, and real performance gains. Message us your exact cam and vehicle setup before or after purchase so we can build it correctly for your combination.

1
Base Tune — Stock Truck

For stock or lightly modified HEMI setups — intake, exhaust, headers. Fixes GM's lazy throttle calibration, improves response, smooths shifts, and sharpens overall drivability from the first drive.

2
Cam Tune

Built for aftermarket camshaft installs. Corrects idle instability, surging, bucking, and stalling by dialing in airflow, fueling, spark, and idle control tables for your specific cam combination.

Supported Cam Options

We build the cam tune around your specific camshaft. Message us your cam details before or after purchase so we can dial it in for your exact setup. Popular options include:

  • Texas Speed Chopacabra HEMI Cams
  • Texas Speed Stage 2–4 HEMI Truck Cams
  • BTR Stage 1–3 HEMI Performance Cams
  • Sloppy Mechanics HEMI Cam Profiles
  • Scoggin-Dickey (SDPC) HEMI Truck Cams
  • Other aftermarket HEMI-compatible cams — ask us if yours isn't listed

What We Need From You

  • Your HP Tuners factory read file emailed to Tunes@JRJonesRacing.com

  • Up to 3 revisions included with every tune

⚠️ Flashing & Safety Notice

Flashing your PCM can be dangerous if not done properly. Follow these steps to avoid bricking your PCM:

  • Never flash over Bluetooth or Wi-Fi — always use a hard-wired USB connection
  • Connect a battery charger to maintain stable voltage during the write process
  • Do not interrupt the process once writing has begun

J.R. Jones Automotive & Performance is not liable for any PCM or ECU damage resulting from improper flashing or unsafe tuning practices.
