4200 Firmware Update

I have several 4200 060-D242-A65 with the A3S firmware from Bell and I want update them to Siemens generic A8M firmware so they have better market value and features when I sell them.

I updated one modem with the update_D240_A8M_106-65_1210_v1r.exe firmware and noticed the performance was actually worse then with the original Bell firmware

Upstream Train Rate before: 800000 / after: 704000
SNRC before: 11 / after: 6
CRC Errors seems to be going up faster as well

Is there a reason why the generic firmware performs worse and is the Update_D240_A8M_106-65_1210_v1r.exe version the latest generic version from Siemens ?
