Just make sure the modem doesn't have an attenuator on the back, between the coax and the modem. If it does, just take it off and see how the power levels are.

noticed the modem had an attenuator plugged in, took it out now get these readings

Downstream Lock : Locked
Downstream Channel Id : 0
Downstream Frequency : 402750000 Hz
Downstream Modulation : QAM256
Downstream Symbol Rate : 5360.537 Ksym/sec
Downstream Interleave Depth : taps32Increment4
Downstream Receive Power Level : -2.4 dBmV
Downstream SNR : 40.8 dB

looks good to me
