I would say that all readings on the log look fine when viewed in E-Race. I dont see anything odd in Excel either. There are some rpm rises when on full boost/load. But they could be a little bit of wheelspin, clutch slip, or just down to the road surface.

I dont see anything strange in that log at all ?

I think is the Road surface because the
road i make the tests runs is not very flat.

I cant think what would be causing it.

Did you ever do a log of driving ( 10Hz is plenty ) with all wheel speed parameters being logged ? Basically log as much as possible.

I use the GT101 sensors on mine, and it just works at all speeds with no problems.
