    Duramax DEF delete

    Father in-laws wants to delete the DEF and install 5” exhaust on a 2016 Chevrolet 2500. Is he going to need a Tuner to perform the DEF delete.

    Yes he will need a programmer. Efi live auto cals arent bad, if he wants to see data with gauges and what not I’d look at ez lynk. PPEI tunes are nice and make good power. I GDP isnt bad either.

    We usually use EFI Live but EZ Lynk is a great option. We use PPEI Tuning

    CTT and PPEI are awesome choices. I like CTT because they are a mixture of a couple different companies who are leading performers in the industry under one roof as of this month.
