OK guys here it is. New to forum new to diesels, I have a 2012 Ram DRW with the 6.7 cummins auto transmission, I want to do a EGR delete and a exhaust delete. Question I already have the EGR delete ( kit was thrown in when I got truck) and know I need a tuner before I actually do the removal, can I purchase tuner now do the EGR delete then later do the exhaust delete ( from what I have read going with the MM3 and DRD ) does the MM3 have to be updated or anything once I do the exhaust? Secondly I joined the forum on a year membership but looks like need to be a life time member to get access to DRD any way to upgrade without having to pay the full price (should have done it first I know). Thanks for the help
