EFIBYRYAN 2006-2009 5.9 & 6.7 Cummins Custom Tuning.

Please fill out the information above to the best of your abilities, use the other info box at the bottom if you have pertinent information to your custom tuning. Expect 1-2 days order processing time for your Autocal as these are made to order.

30 days of custom file update support is included with purchase to ensure the file is setup properly and maximizing the potential of your individual setup. File update support after the initial 30 days will be considered a re-write and will be a flat rate $100 with an expected turnaround time of 1-2 business days. File support is non transferrable to other individuals or vehicles, this would be considered a new purchase unless special circumstances exist (vehicle total loss, theft, etc).
