slowing a spool up doesn't help them controll the engine, probably adds stress rather then reduces it too, it creates a surge of boost rather then then a smooth transition which can't be good.

they are giving a 100,000 mile warantee on the engine and we can't blame them for making sure there is no more pressure then they think can hold out for that stress

however this solenoid would add stress to the engine in my opinion and I am wondering how pontiac thinks it benefits the power plant
