my car runs fine under boost BUT when im cruising down the highway with the supercharger set at low(being the high setting) and the throttle is below 5%, meaning the supercharger is not engaged and i am not making boost, the car periodically seems to stutter and the a/f ratios go lean. im guessing this is preignition. this happens maybe once or twice every 10 minutes or so
now when i have the supercharger turned off this does not occur.
