Saw this as a topic of discusion.. http://www.superchargertuning.com/Chevrolet/Silverado/ Voltage Stabilizer for noise to the spark plugs?? Is this really up to a 10hp gain? Fuel management chip for sensor near airbox(mafs) im assuming? up to 10% hp/tq gain? I guess the magic word is UP TO.. Kind of funny on how it says on the home page works up to 5.0liter engines but are discussing the 6.0 liter under chevy silverado.
