Hey guys I just bought a new 2016 Midnight Edition 2500HD 6.6 Duramax. Wondering what are the recommended delete kit for 2016 durama besides DPF and EGR delete. Not looking to turn it into a dragster, just want great reliability and best mileage possible. For example should I add a lift pump& filter/separator combo? Oil filter relocation kit? Also please let me know if these will void the warranty or not.
