How tight is the piston seal in the cylinder? It could bed in and become more efficient. Otherwise, maybe a power washer behind the spring?

If the seals a bit loose, you could lose power there. For interest; why remove a coil and collapse a coil before getting to 9.5ft/lb? It sounds like the spring in its' original guise would have met your requirements.

Did you not try everything before you took the coil off ?
