Sims will let you delete the dpf without needing a tuner and you may be able to just unplug the egr and be fine. It's hit or miss getting a cel. Next would be getting a smarty/Mads tuner that allows dpf/egr delete. They will run around $800. Then is h&s xrt pro race. It's similar to the smarty, hand held, you'll have to retune each time you want to change the power level. These will run $1000-$1500. And the most expensive is h&s mini max/black max. These will run $1000-$2000. These allow change on the fly power levels, choice of 4 gauges. The h&s tuners also support custom tunes.
