I have just spent the last three weeks in hot and high conditions with my C-130 (C-130K with H model engines).  There is not a cat in hells chance that any simulation could correctly copy the real aircrafts TIT and fuel flow indications.  

You can never get all four engines to function with the same fuel flow and TIT indications.  No matter how hard the CS team could work at it, it would be impossible task to achieve.  Part of my training covered engine runs in the full all singing and dancing full motion simulator.  That even had the same readings as the CS model which I believe is based on the same simulator.

I sent the CS team a copy of a table from the Lockheed operating manual.  It gave expected indications for certain conditions.  This covered Fuel Flow, expected TIT against altitude, weight and temperature.  The number if different indications on the table would take a lot of include in any simulation.

To be honest I think the CS model is going to be the closest it will ever get.  A tweak here and there may help but in the end it is still a pretty dawn good product.

On another note some of the things we did in Albert can't be done on the sim. Boy it can't half fly in the right hands...I tried and on most occasions I cartwheeled down the runway or put the bottom of the frame through the runway.... :o :o
