Okay, I ordered a Lund tune but I'm now having second thoughts. I bought my 2014 in May and have had zero issues with it. Now that I started ordering a tune it has turned into I need to change plugs and gap size too. Lund recommended "Please get some NGK TR7 Plugs with .028 Gap done to them."
So that makes me wonder, if the car has mods and is running great, do I really need a tune? What would a tune do?
