I just recently got a belt mod conversion for my HEQ5 Pro, the guiding is much smoother then it is. But I was expecting a flatter line.
I don't have much mount experience or using PHD2, but can someone point me in the right direction to get this issue fixed?

The 2 sec graph shows bad RA oscillation while the 1 sec the RA is more smoothed out.

PHD2 has the correct focal length and pixel size.
EQmod pulse guide is at 0.30 same in PHD2.
The mount is balanced using the 90 deg angle method.
I am using a guide scope.

Is it a PHD2/software issue, or is it a mount/motor issue?
