I have a 2013 and just completed the complete delete. As for tuning Malone is top shelf and I am running a stage 1. Be prepared for some custom work if you are doing this on your own. They offer raw teck exhaust products, but no one for egr removal bypass.
Big difference you are in for are the smell, she is now officially a diesel. Garage starts are over with. I do notice the timing chain rattle at start up now that the engine sound has changed. Last about 3 seconds then the oilers get primed. This is the weak spot from what I read on the engines. I am a tad over 70,000 miles and still runs good. MPG in over 30 if you keep you foot out of it.
I am typically ford, dodge diesel delete guy. However I stumbled across mine at a deal and wanted to wrench on it. The cars run in some extreme emissions equipment. Amazing they last 100,000 miles.
