A fuel system cleaner that appears to have the "kitchen sink" in terms of solvent chemistry, is this one:
CHAMPION ® Fuel Injector Cleaner
The Champion product does have PEA included.
PEA is a temperature activated hydrocarbon disperser. The other chemicals, even in most PEA type fuel additives, disperse and dissolve varnishes and soft carbon deposits that PEA cannot solve. PEA is not an "end-all."

PEA fuel additives are composed of specialized amines which is the Subject of this White Paper.
The primary use of PEA's in fuel is to control intake valve and combustion chamber deposits.
Amines in various forms are also used as anti-oxidants in lubricants.
Chemistry Classification:
Amines are classified as "Aliphatic Nitrogen Compounds" because these molecules contain at least one Nitrogen atom.
The most basic amine molecule has three hydrogen atoms and one nitrogen atom linked as in:
H
/
H-N-H
One of the primary amines is 2-propanamine Isopropylamine with the formula structure:
H
/
CH3-C-CH3
/
NH2
Most amine compounds are made by the reaction of some form of ammonia, NH3, with other chemicals.
The household version of ammonia is actually a weak solution of ammonium hydroxide, or NH3 in water, H2O.
Fuel Additive:
The actual amine fuel additive is a form of polyetheramine or P.E.A and is seen in blended fuels, and in fuel additives such as Techron and other OTC fuel system additives. The basic polyetheramine is added to fuels at about 50ppm but the level of polyetheramine depends greatly on the components of the blended fuel. Recall that gasoline or diesel fuels are actually blends of various light hydrocarbons of various cuts.
Newer versions of the polyetheramine are actually esterified polyetheramines called, "esteramines." The esteramines adds polarity to the amine.
The polyether esteramines for OTC additives are added to solvent neutral oils at levels of approximately 400 ppm. The basic polyetheramines found in blended fuels are very synergisticic with the newer esteramines.
It is believed that the polar polyetheramine's attach to the hydrocarbon deposit and via thermodynamic activation, softens the carbon. The flowstream across the valves and the turbulence inside the combustion chamber then blow the hydrocarbon deposits to the exhaust stream.
Increases in hydrocarbon loads not only exit the exhaust stream, but can also enter the oil. It is always a good idea to change the oil after using a strong fuel system cleaner.
