I saw there were a couple threads on here about them from a while back. Since I just bought my first 24 valve for my wife a few weeks ago. I decided to give one a shot. Hit my ole buddy Dennis up to ship me one out. Got it Saturday and boy was it easy to put on. Took a whole 5 minutes or so. Anyhow, the box works great. It meets the exact power gains I was looking for. Truck seemed to run pretty good already. This box made it run even better. A+ on the TS MVP in my book. Thanks Dennis
