i have a u7194 for sale it wont work on my 2011 6.2 im asking 250 obo will deliver to dfw this weekend call or text 325-829-0198

 

Will it not work becuase of the size of the engine? If this is not the case, and it just won't load a tune, you have to contact Diablo for an update. Everytime the new trucks come out, they update the database to read the new VIN. If yours was manufactured before your truck was, it will not recognize it. U7194 wouldn't work on my 2010 Silverado until I called...

 

^true had to do it for bulldog I put on my buddies!! They are in denton and did it right at the shop!
