I did a search, and didn't really see what I was looking for. I've seen kits that offer much more including wastegates, then I've seen some that are just block off plates. What exactly are the benefits of the EGR delete kits? Can buying the block off plates be beneficial? I'd like to run the larger tunes with a small shot to get in the 12's. Even more importantly, will this help with fuel mileage? Any help is very appreciated. Thanks.
