I have done the Cali. deletes, Is there any advantages by doing the full deletes ? Any gains in MPG, ets. 2007.5, 6.7, Smarty JR.

 

did you gut your dpf and cats? doing full deletes gets rid of a potential leaker EGR cooler.

 

More $, more time, but you can clean things up and make room and eliminate some potential other issues that these emmisions bring like the EGR cooler leakage potential. However, the operating principles are not really any different or changed between full or cali I have to smog mine next month, so I am very glad I did not do any full deletes. Easy off, easy on. There are some experts on here that can change full deletes back and forth blind folded, but for the average guy going back and forth is a pain I think. Also, who wants to store more of this stuff anyway. I do not recommend permanently getting rid of any emmssion whether it is full delete or the basic cali style, and keeping it on hand for the various time needed. Like warantee, smog, sale, etc.
