I really like the truck and in the near future want to start putting some money into modifications (not engine related--yet) but wonder if I should just keep it stock, save my money and sell it in a couple years and buy the new model (2011-later). I think one of the big determining factors is wether or not I could rely on it to get me to 250-300k miles. I realize it won't be completely maintenance free, but don't want to have to expect major overhaul's. I don't plan on tuning or doing anything at this point. I would entertain an EGR delete once Warranty expires or something else that could add to reliablility and longevity. So questions are: How many miles are you seeing in your 2005-2007's? & What mod's are a must to gain real longevity in your 6.0?
I realize there are probably many posts already on these topics, so links to good threads are appreciated. Thanks, and I look forward to learning from you.
You might want to check the links in my signature. Number one reliability mod is to flush the cooling system and switch to a Cat EC-1 rated ELC coolant. Then delete the EGR as soon as you can. Those to things alone will do wonders for the reliability of your truck. A good monitoring solution is a necessity and not an option. If you are not already monitoring your ECT and EOT you need to to determine the health of your oil cooler. The best bang for the buck is the Edge Insight. A nice 4" cat back with a cat delete, and an SCT X3 with tunes from someone like Eric, Matt, or Vivian will keep you smiling from ear to ear and keep your truck reliable too. Add a coolant filter and a bypass oil filter and drive it. That's all you really need to do to have a really enjoyable reliable truck. And be anal about routine maintenance. I strongly suggest a good synthetic oil in 5w40 changed at 5 or 6 thousand miles. If you choose to run dino oil consider it used up at 4k.
There is plenty other stuff you can do but the above won't take you broke and still give you a real fun truck. If that gets boring you can always throw a Powermax Turbo and a set of 190cc injectors in it and tune it to about 550 rwhp. After that you are talking exponential dollar investments for the returns.
Oh yeah. Do the Insight and the coolant flush and change over asap. Neither one will affect your warranty.
