I'm ready to tune my truck, which is stock right now. I've never used a tuner before. Which is easiest to use, and has the best gauges? I'm looking at an SCT Livewire with Custom tunes from Eric at Innovative. Or a H&S Black Maxx with KEM Custom tunes. I'm going to buy a complete Delete setup as well,(DPF and DOC). Now for the hard part. Which is better?
