Getting rid of mandate

[flonly]

Ok So I am new here so let me see if i am correct .To do the mm tune I need insite and internet connection and i would be able to possibly get someone to remote download to my ecm.Now no hardware is removed but the tune stops all or most exhaust gas from being circulated back through motor plus other tweaks ?Resulting in less regens ,cleaner oil with less abrasive soot in it,cleaner sensors,and premature engine wear?Now i am no genius but is this tune teachable or is it to complicated to learn as more of a novice computer user.I have done egr tune up several times but that is mainly turning wrenches and following great videos from rawze.
