    j_martell's post in Powerleash was marked as the answer   
    the granite i used to run has a powerleash, it worked not bad concidering it was on an 11 litre motor...its a compression brake, sorta like a Jake Brake.....opens the exhaust valve at the top of the compression stroke....basically using the vehicles momentum to run the engine as an air compressor to waste kinetic energy.....
