My on 80 HP economic tune is very noticeable. Worst is running down the road about 55 or so. Actually any steady cruise speed. Bump it in to stock and instantly quieter.
Same here, I thought that was "normal" so I learned to deal with it. I didn't realize that the tunes were supposed to be close to stock in terms of noise.
