Found a cool shop with a bunch of truck tuning parts, checked that the business is completely legit. Ordered a kit for my ford, delivered pretty fast, just a couple of weeks, and free, which is a small thing, but nice. Now my truck handles heavy loads much better. The engine roar is great, the performance and handling has increased noticeably, I'm even thinking about getting myself a workhorse for offroad fun DPFDelet.com
