Ordered a 15 6.7 and just put my dpf back on my 13 today so I won't need my xrt pro anymore. Bought it 2 months ago from Will at Rudy's and it's for 13-14 6.7s and you don't need an unlock code or vin to use the tuner! Located in SE Pa 45 minutes west of Philly. Looking for $1200obo, I have paypal.
