I just got a diablo power puck and i can not believe how much more balls my truck has now. I know its just 50hp but you can def. feel it. The whole truck just runs alot smoother especially when you need to pass on the highway. O ya and when you leave a stop light it will set ya back in the seat pretty good. I can not believe how much of a difference it made, and this is only the beginning of my 400hp journey haha. I still need to hook up my raptor since it will sometimes cut out when i get on it, i can only imagine how its going to be with a steady flow of fuel haha.
