Fleet of 2013 gm 2500s, used off-road only, don't need high performance, probably better if there wasn't hot rod buttons for monkeys to touch....

Looking to solve the reliability issues, one truck is currently bricked with a "def fluid quality poor-3 miles til 4mph"

Will a delete and tuner solve that issue, or does that "tamper" still need resolved?

What's the go-to these days? What's the little things that need to be bought with it so I can get a complete quote?
 
I was told EFI live and delete pipe on my 15.5 would solve my issues. Waiting in parts to get back in stock, was told this week.
