Autopilot banking question

[Ethanet200]

I'm curious about an aspect of the 146 while using LNAV on the AP. I follow my SID / flightplan however everytime lnav overshoots the planned turn and it always ends up having to recorrect to get back on the flightpath after the turn. Is this a limitation of the 146s autopilot capabilities? Or is there a bank angle setting I'm missing?

Is it possible you’re flying to fast for the turn, ie beyond the airframe capability.
