Whipple Superchargers

Hello everyone, does anybody have a link to info or personal experience on correct test and or maintenance procedures on these? I have one here in a 99 Denali and its burned some valves and or pistons. Fuel pump refuses to cycle and I get the pleasure of figuring out what happened. The owner said it still roasted the hides even when it didnt run right. Any info whatsoever is greatly appreciated. :banghead:
