PA28 Turbo Arrow IV - Leaning?

[Egbert Drenth]

Hi,

I posted this on the AVSIM forum, but I should have posted it here...

"I'm a bit puzzled by the Justflight PA28 Turbo Arrow IV....
Disclaimer: I'm not flying single engine props that much, so it probably is user error 😉

Current I'm flying a 8000ft and I want to lean the engine/mixture.
However the moment I lean the engine, the fuel flow increases ?!?
Without leaning: ~ 12GPH, when leaned: ~ 15GPH
Is that correct? I'm a bit puzzled.

P.S. I'm talking about FS2020"
