Props can't reach max RPM at low A/S, ITT spikes while taxiing

Saab 340 V1.51 in XP11.26.  I've noticed that the props can't obtain the full ~1400 RPM below 80 knots.  They just won't come on the governors without a ton of airspeed.  At 100% TQ, the best I see is 1225 RPM.  Likewise, on final, the props will fall off the governors well before I reduce power for the flare.

A separate issue:  when transitioning between GND IDLE/beta and FLT IDLE during taxi, I see some huge swings in ITT (often shooting up suddenly to 1000 deg) and the prop RPM swings up to like 1300.  My throttle quad is an old Saitek and it's getting kinda spikey, so I disabled those axes and used the mouse to manipulate the P/Ls but had the same result.

I'll add that I just read N1K's thread and watched his video.  I am seeing different issues than shown there.
