Hi. Next to cost the same machine, works with the same parameters and on the same fuel.
We think that the problem in the turbine. Who has experience in diagnosing a turbine?

So, I think your problem is a high humidity in fuel, in fact the fuel air ratio is completely wrong, the fuel throttle opening factor is at least 5% below the normal opening required, after checking the specific fuel weight, and testing,

The problem is the following when the engine is fully loaded Throttle Position 100%. So the engine slowly reduces the load.
The cleaning of the fuel valve. Replacement of sensors In Man Pr.(abs).
T/C outlet pr.(abs)=340kpa
In Man Pr.(abs)=340kpa
Throttle Act pos command=100%
T/C comp bypass valve pos com=0%
Mass fuel flow = 347
Gov type setting=isochronous
Eng speed droop=0%
Actual Air to Fuel Ratio=27.9
Fuel valve pos=60%
Fuel valve diff press=30kpa
Gas spec grav=0,6
Actual Charge density factor=1.1
Desired Charge density factor=1.15
Gas fuel corr factor=85%
Inlet air temp=47degC
I can send the engine work file .sdf
