So... ... ... I have spoken to several cummins guru's and have been told the best setup for my 04. 5 ram I would be a smarty S06 downloader stacked with a TS Performance MP8. I currently have a Van Aaken C5 Smartbox (adjustable 5 level 180hp) programmer. I know... ... ... ... . old technology but it works really well. 5 inch turbo back exhaust, banks air ram cold air intake w/super scoop and banks high rise intake. Air dog fuel preporator supplies the fuel to a stock pump system. This combination has shut down more Duramax and Powerstrokes than I can count. I know the addition of 100hp injectors and a Aurora 3000 would be fun, but I need this vehicle to be bullet proof. I use this truck to run expedited freight shipments into the hinterlands of Minnesota, North Dakota and Wisconsin. Can't break down in the middle of nowhere. Anyone out there running the Smarty/TS Performance stack that can give me a little feed back on what to expect?
