Have a VIN unlocked Smarty Jr., and Flo Pro delete pipe (with downpipe). Had this setup on my 2012 Cummins for 16,000 miles, worked flawlessly. Horsepower increase of 0, 40, 60, and 100. Just traded truck in, returned it to stock. Can program any tune into it for buyer before sale. Tuner itself will work for any 6.7 up to and including '12, but the pipe only fits '10-'12 as far as I know. $750 nego picked up for everything, will separate. Text 412 five three seven 8903
