not like telling you but you're lean gas, if the red curve is the gas air ratio you're out as a missile, you have to stand on the 18-1 16-1, no other than otherwise there is a tool reading problem, you controlled the output

Hi.What time of engine operation, in which country do you live,what is the air pressure before the throttle and in the intake manifold when the engine load is 100%, what is the temperature in the cylinders and exits the turbine, the temperature of the air flow throttle valve, the control line pressure differential throttle working properly .

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,
