The bully dog is worthless except for the extra gauges and there is no point in doing an exhaust unless u do it from turbo back and that means u need a tuner that lets u delete yer dpf. Thats just my opinion!

Better to go turbo back with the exhaust. And after this stuff is done you should see a decent increase in fuel mileage.
