Very strange...

...
...correctly Trimmed, I can squeese 220 knots out of my FS 2004 Default Beech Baron 58 Twin in level flight...(and keeping a wary eye on all the Gauges at the same time!...

...!
Which is why I always use her for my long-distance, piston-prop flights across country...

..!
My favourite cross-country Tourer.
F...G-BPLF... 8-)...!
She is as fast, or faster, and nippier, than my Default Beech King Air Turbo Prop Twin...

...

...!!
P.S....always make sure if you have been running on Auto-Pilot, that you RE-TRIM the Aircraft after you have switched the Auto-Pilot off, and every time BEFORE take-off!
Never forget your Trusty Trim-Wheel at all times!
