Hello, I have owned my Veloster turbo for a few months now. A little while ago I started experiencing surging during WOT. I took the car into the dealer and they replaced the turbo pressure sensor. Get the car back, still surging. Hyundai looked at the car again and noticed that the fuel pump was failing. They replaced the fuel pump and the issue went away for a few weeks. Except its back again. Most noticeable when in 3rd gear getting onto the highway. It feels as though the car is falling in and out of boost. Does anyone have any ideas on what this could be? Car is 100% stock and is 6 speed manual.
