Problems with SR 22T G1000

[Kronos22]

Hello,
I need your advice: I acquired your Cirrus SR22T G1000 beautifully modeled, but with which I encounter major problems of use. I agree it is sharp, the engine settings are remarkably reproduced...
I follow the tutorial recommendations of the excellent "Reflected Reality Simulations" to the letter, but I have never been able to make a flight without problems.
Like him, I go up to 2700 rpm but I can't hold it without important variations of the rpm.
In cruise, idem I set it at 2500, I play with the fuel flow, it holds a little, more or less long to find this "vroom, vroom" of the rpm oscillations, with the needles which oscillate without stop. I am very attentive, but nothing to do. I even tried to remove the plane and reload it, hoping to remove a possible engine problem, without result.
I would be very happy to have an advice to remove these inconveniences, because I am really a fan of this plane.
In advance, thank you, with my most friendly greetings.

Daniel
