It's good as in if the fuel ECU is faulty. Other than that (and if fuel pump getting weak) it is pointless.

People say it is bad on the system, it does shorten the life if the pump by 5% (approximately). You don't have to worry about too much pressure as our cars have a return style fuel system, it will just keep cycling. I've done it to mine and no issues yet. Still stock pump with a march91 production date and 160k miles
