The Gumout cleaner without the mention of PEA is probably the "fuel injector cleaner" product and I believe does not have ANY PEA additive at all.
I also recall hearing that once any product with PEA reaches 50% that is the maximum effectiveness you can get, anything over that and it isn't any more effective at cleaning.
