Can a leaking/faulty dumpvalve be the cause of oscillating boost?

Yes. Another telltale sign is an unstable idle......

So, you think it could be the reason for my car to
feel like its overboosting/surging in gears?

When I accellerate hard in 4th and 5th gear from approx. 3000 rpm, sometimes I hear a sound (hissing)like there is air escaping and the power drops to be picked-up again etc. For your information I still have the OEM dumpvalve fitted.
