I live in California and own a stock 2010 with the 6.7, auto. I would love to have a programmer in the truck to help wake it up a bit. It seems a bit sluggish. I don't plan on hot rodding it, but more or less would like more power and better mileage. I'm just not so excited about a DPF/EGR delete and then putting it all back when it comes time to smog. Yep CA sucks for that kinda thing. Any imput other than telling me to delete would be great.
