Bode plot dB vs calculated dB

[Telephos]

I'm using an op-amp and the calculated results don't match the results bode plot results. If I calculate the gain from the voltage output to voltage input, I get a drastically different value at higher frequencies. Below you can see I have a standard inverting op-amp configuration for a gain of about 14.6. At 160kHz, the calculated dB is 3.0, whereas the bode plot says about 14.7 dB. Even the frequency sweep claims a much higher magnitude for the voltage output than what is reflected from the voltage probes. This is not an issue at low frequencies (5,000Hz).

Using a real op-amp (LM741) I get similar results from the calculated dB and experimental results.

Thank you in advance for any help.
