Good evening, I have a 2019 GTN Line and its my first boosted vehicle, as its hard to find a good naturally aspirated engine in what I want. Anyway, when accelerating from 3-4k rpm, sometimes I get a surging feeling. The dealer says that when thats happening that the wastegate is on the threash hold of being open and closed. I know there is an aftermarket wastegate solenoid out there that can fix this but I don't want to void any part of my warranty for something they should tune properly. Anybody else experience this? Also, I was thinking if I had more air flow with a K&N filter or even an intake, that could help. Your thoughts?
