Still having issues with the new LQ4 build. When the car is being driven around the first 10 mins or so the STFT's will randomly jump to -43%. I did headers with the swap so the Air Pump was deleted. The odd thing is that the only time the STFT's jump to -43% is when the pump turns on. It just makes a loud whistle noise, still need to pull it out. What could cause this? I'm leaning towards something in the tune.
