This is nothing but an opinion, and from experience with carburated vehicles.
If the vehicle has been using fuel system cleaners its entire life then it works well and will keep things clean.
If it has never had cleaner in it and has many miles I feel it knocks so much crap off the side of the tank and fuel lines you stand a chance of making it run worse by clogging filters or injector holes.
It happened twice to me on older vehicles years ago. I wouldn't take the chance, just my opinion though.
That is one thought that did cross my mind.
