It was sooooooooooo easy. Took about 40 minutes because I read the directions about 10 times. Everything fit perfectly and the only thing I would advise is that if you are planning on getting a TB too, get it and install them at the same time. It will save you some time. As for any increase in HP/TQ, my SOTP Meter was telling me that I had gained some HP/TQ but I have no clue how much. Overall, its an easy mod, relatively inexpensive, and therefore worth it IMO.
