Ok so I've been dealing with a couple different tuning softwares for about a year now and I'm getting ready to try to tune my 15 Cummins, from what I understand I'm gonna need a .cax file to delete the dpf and other after treatment stuff in the exhaust. I have a template for what looks like ls1 operating systems, with this file could one just convert it to work on a Cummins or do I have to get a different file? Also is there a specific program I need to modify this file? Any advice on this topic would be appreciated thanks.
