Need hydraulic steering help

It seems I have a mismatched hydraulic steering system. It has a Sauer-Danfoss /VERADO helm which is rated at 3.05 Cubic Inches of volume. The cylinder is and unknown brand...the pump is the factory GM pump on the engine. The problem is the cylinder takes too much volume for the helm. So it takes over 8 turns lock to lock.
I have already changed the helm to a faster unit...the fastest one I can get without changing all my hydraulic lines...and that helped a little, but only a couple turns....I was at 10 turns lock to lock before this.
So now I am thinking I need to get a faster cylinder. One that will move quicker with the helm volumn I have.
I need suggestions, I am open to anything except spending $1000s on a complete new system.
Here is a pic of the cylinder I have....anyone know who makes it?

Phew, that's a vague question, hard to tell by just one photo. I'mnot a hydraulic expert but in my experience you may have two things to look at... Pump volume/pressure and cylinder flow. I'd take the cylinder to a local hydraulic outfitter and have them take it apart. I think there is a means of lessening the restrictions to allow more flow so the cylinder works faster. Something seems quite wrong though, 10 turns lock to lock is allot! This isn't a cruise ship!;)
 
Thanks for the reply.

I called Ron at Imco and I think we have a solution worked out. I ordered a 95CC steering helm and new hoses. According to Ron's calculations, that should give this cylinder 2.5-3 turns lock to lock. I will post the results once I get the part and get them installed.
