Anyone else have this issue?

Fuel lines were changed along with both pumps.

Could be driveline vibration. Start with simple things and then work your way to more advanced issues.

Start with checking motor mounts, transmission mounts, and vibration dampener. 

Was the calibration updated after the pump was installed?
