I wish I did my dpf delete and tuner as soon as I drove my 09 off the lot. Im getting MUCH better mileage, better driveability, cooler trans temps and now its more reliable. In short, I now love my 6.4 where before I liked it but there were a few issues I had to live with. and for 6.0's, look for an 06 or 07. Our 6.0 has had less problems than our chevy HD with the 6.0 (i know gas vs. diesel) It now has egr delete, studs and a full buildup along with a tuner. I would consider an egr blocker or delete as vital when you get a 6.0. That will solve about 75% of the problems of the truck. In short, I too had a disliking of powerstrokes, but after reading and gaining knowledge on the subject, not just spitting out heresay from others, I'm glad I went this route.
