Hey there everyone.
I'm new to the tuning world (HP Tuners anyways) and just currently picked up an MPVI2. My 60 yr old mom has a 2018 Chevy 1500 5.3 and asked if I could shut off DoD and possibly up her MPG's. Can someone shed some light on the areas i should adjust/look at? I'm not asking for someone to write me a tune, just a little help. The search bar and I don't get along, trust me I've tried. Thanks everyone!!
