This EFI Live Custom Tuning Revision is a great option for updating your truck's tuning. It fits 2006 - 2022 Dodge Ram with 5.9L or 6.7L Cummins engines and 2001 - 2016 GMC with LB7, LLY, LBZ, LMM, & LML 6.6L Duramax engines. Note that these are only tune file updates. You must have previously bought CCS, AMDP, or Proven tuning and need an EFILive AutoCal Device to flash the updated tunes. Whether you've made new modifications or just want more power, this revision will meet your needs. It's for existing customers to update their current tuning. Part Number: TUNE - REV - EFI. The process is simple: choose your current tuner, enter your VIN number, list all your modifications, pay, and you'll get your updated tune file via email in about 1 - 3 business days. Then flash the new tunes onto your truck and enjoy your new mods.

How to use: First, pick your current tuner from the given list. Then enter your vehicle's VIN number. Next, write down all the modifications you've made to your truck in the 'MODS' box - the more details, the better for the tune. Pay for the service, and you'll receive the updated tune file in your email in about 1 - 3 business days (this time may change based on how busy the tuner is). Once you have the file, use an EFILive AutoCal Device to flash the new tunes onto your truck. Notes: This is only a tune file update. You must have previously purchased CCS, AMDP, or Proven tuning. Maintenance: There's no specific maintenance for this tuning update, but keep your EFILive AutoCal Device in good condition for future updates or changes.
