If you have the $$$, do it man and you will love it. I just got back from Tahoe California towing up a 6% grade at 7400 feet 95 degrees outside air temp and all I can say is the stock truck pulled great at lower elevation, but at 7400 feet the pedal was getting mushy. Packing that fresh air into the engine is going to improve your towing in a very noticeable manner even at sea level on a hot day. I want to get one so bad because it takes our horsepower up to 500 and our torque from 400 to 550. That 550 ft pounds of torque is equivalent to a mid size diesel engine.
