Do they really add that much HP/Torque to the truck? Most chips I seen are 150hp/200+ torque, but their chips just seem to blow those out of the water and add 290hp/405tq. It just looks insane. Granted I know you'd need a new transmission that could handle that, but I've always wondered. A few I seen are even like 350hp/605tq, but those are for the slightly older MY's.
