Already had multiple issues in the past and not sure if it's worth hiring someone else to retune the car.
My tuner said there is no detriment to result from it. Perhaps all you need is a fresh set of eyes on it. Mine does it still but very slightly, meaning over a much smaller rpm band range (~300rpm) as opposed to ~1000-1200rpm. Everything else looks bang on otherwise but I will keep a close eye on it when temps drop below zero.
