ok, i got my new power pup for my LBZ. It came with 1.07 and it loaded with no problems. Other threads say only use tow/economy, dont even think about towing my camper with performance or extreme. So I installed the tow/economy on my truck. Whats the big deal here? I dont belive I can see or feel $400 worth of extra horsepower, what do you guys think?
