We do quite a few of these at our shop and have used EFI live H&S, Smarty, and RaceMe software. All work just fine. With that said, an EFI custom tune would be my recommendation. There are lots of people that provide these tunes but you need to do your homework on which one works best for you. You can have multiple tunes as well with this setup utilizing a cps5 switch in the dash to change on the fly. As far as the deletes it's not that big of deal to do and and can easily be completed in a day. This includes removing the EGR, EGR cooler, and all emissions equipment in the exhaust system. We usually use FloPro exhaust delete pipes and Sinister diesel EGR delete plates coolant bypass.
