It is very likely an unfortunate confluence of factors. For example, maybe your wheel gauge is just a bit close to marginal, and the position of the guard rails (or the wings) leaves too much slop for the axle to track accurately with the flanges doing the work. Sometimes placing a thin plastic shim, say 8 thousandths of an inch or a bit more, on the inside face of the guard will prevent uneasiness at the frog.
The other thing is that curved turnouts are msomewhat tighter in radius on the inner route than the manufacturers would have you believe. This is particularly true with the Walthers/Shinohara curved turnouts. I can't say about the Pecos because I have no experience with them.
