these shops don't care they probably want the bad tuning because its a hedged bet for more business as that truck comes back 6 months later for a head, turbo, inframe, out of frame windowed block, and other issues they create.

this is why i trust my shop they will not recommend nor have tuning done in their shop and will tell you that if you want to tune it you are probably going to wind up back spending more than fixing the issues with the emissions. they will work on them after their tuned of course but will not help getting it done. they don't have the expertise for it nor want it. he always says im a mechanic not a computer programmer and i don't want to become one.
