The 550 doesn't make much power under 2500 Rpm. Without bumping it even higher you are getting about all you can out of it now.

Can you add more shims to compensate? or would you just want a stronger spring?

Would have to go to a stiffer start spring. Any more shims and you risk it coming out of the pocket, and it could bind up the spring on full shiftout too. Going higher will make it very difficult to maneuver at slow speeds and make take offs very harsh.
