Thanks Ozer. I'm not so sure about the tune to remove the exhaust components given that I'm in California and all the required smog checks. Did you have to/end up doing any preventive maintenance between 85-100k? Like Waterpump, Turbo, EGR valves etc? How long do you plan on keeping the car for? I'm hoping to take mine to 150k. given that I drive about 20k a year that will be 4 more years and at least 1 year after the truck is paid off.
