There have been a few bugs but the shop has been quick to deal with them and things seem to be working great now. I have a 6-spd manual trans in my truck and I had to replace the clutch right after as it wouldn't hold the extra power but apparently the stock clutch in these trucks are borderline as it is and life span is not great, but just a heads up as to going down the rabbit hole so to speak, one thing leads to another. Cons of the whole thing would be some black smoke that I was told wouldn't happen but does under certain instances, mainly stepping on it at lower rpm but other times as well. Also with all of the emissions stuff being removed, the exhaust has that raw diesel smell so if you're adverse to that its another thing to think about. All in all we're pretty happy with the results. I had issues with the emissions equipment on my truck from early on so that was the main reason for me getting the work done, altho the extra power and fuel economy is a nice bonus as well.
