Question about programmers
 

I have a 2008 dodge with a 6.7 cummins. Let me say it's an awesome engine and and everything about it... Except the emissions. I know big shocker, I'm looking a delete kits now and am leaning toward the efi live. I was wondering if anyone can tell me if I get and edge insight cts if it will adjust the efi live on the fly or do I have to plug the efi in if I want to change power levels. Thank you for any help I appreciate it.
