the underdrive pullys will give you a slight HP gain but i dont think you will notice it. the e-fans are the way to go because you take a big load off your engine by taking out that damn fan clutch so your gas miliage will improve. and a little HP gain. all of it wont be a shocking difference but you may be able to tell. In my opinion, its a good idea to install. you will have that peace of mine that your engine is not working as hard to push you down the road.
