Flashing & Safety Notice

Flashing your PCM can be dangerous if not done properly. Follow these steps to help avoid PCM or ECU damage:

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

J.R. Jones Automotive & Performance is not liable for any PCM or ECU damage caused by improper flashing, unstable voltage, incorrect file use, or unsafe tuning practices.

Important Notes

This tune is for BTR Truck Norris camshaft setups.
This is not a universal canned flash. Your file is adjusted using your stock read and modification list.
You must already have, or purchase, HP Tuners or EFI Live to read, flash, and write the tune file.
For best results, include every modification on the vehicle before the tune file is built.
