I read your write up which i think is soooo good.
How do i go about having original file's installed into my truck engine?

You dont need the original Cal (calibration file), but you do need a compatible Cal. Rawze has a list of tested Cal compatibility in the linked page in my previous post. You can update your Cal to Cummins latest version using InCal Disks.

This post really is the best starting place http://rawze.com/forums/showthread.php?tid=1&page=7
