Sure, but the ppp lcp negotiation is only between you and your EVDO device. It has no correlation to the parameters of the mobile network. > If I "set mru 900" it's stable.

I suspect that unless told otherwise, my devices negotiate a minimal parameter set for the PDP context, which the vendor drivers override. Cell congestion is normal here, so achievable throughput is a moving target. Difficult to compare like for like.
