CS Legendary C130 Engine data in aircraft config file

I need some help in improving the engine simulation in the aircraft config file.At the moment, the parameters do not match the T56 from real data, but changing some of the figures (N2 speed, reduction ratio, min governed rpm) to 'real' values makes the performance fall off, the fuel value to drop but the torques and PTIT to become more realistic.I guess it's a case of juggling all the engine/prop parameters, but I don't know what all the parameters relate to, and was wondering if anyone had enough experience/knowledge to point me in the right direction. I do have the SDK and its explanations, but some I just dont have a clue what they actaully relate to.It looks to me as if captain sim have lightly modified the config file for the Dash 8 model for the emgine information, as they have so many parameters the same that I can't explain it in any other way.Hoping for a reply to this and some assistance in this area.
