My knock sensor has been turned off for over a year now. There not accurate. I have logs of it picking up noise from the wastegate and it would pull 2degrees. Also when I would shift fast it would think it was knock and pull 5 degrees then slowly put it back in. As long as your tuner knows what he is doing there should be no problems. Also I fill up at any gas station. Hess, Bp, sans club. Etc.
