Put in my shiney new Jkidd 435s today. Put them in 2 hours with no problems, truck fired right up. The haze slightly more than the stockers warming up, as expected, but not bad at all. When I put my foot in it the turbo goes from 0 to 30 in about 2 seconds and my club cab takes off like an acme jet rocket! Smoke and temps are better than I had hoped with an h1c. By the time it hits 1250 I have to get my foot out of it cause by them its moving pretty fast. Meth kit should be on the truck by the weekend for even more fun, and a bigger turbo is coming soon.
