Ok folks. I've about gotten out of the max'd out duramax mindframe and want to just be happy with what I have now. (kids planned in the next year) so with mods in my sig what are some suggestions to be done to ensure a long life from my duramax. I'm changing the oil with amsoil and filters. Suggestions not limited to anything. I need advice on front end and motor. Rarely pull or race. Just want a good looking and durable truck for years to come. I have the egr delete and PCV reroute kit in the mail and plan on installing next week. Lemme hear em. I am thinking efi just for mileage but I'm getting 19 or so hwy with my edge and 15 in the city. No more built trans and twins in my future.
