I just got tuned today and my tuner "turned off" the p0300 code. Now when it's idleing the SES light flashes a few times and quits, then in a few minutes it starts again. When I scan it, after or during the flashng, I have no faults found. What's going on?

Sounds like the car may be getting a false knock then going away. If its not continous then the car won't throw a code

Usually when the SES flashes it indicates 'random multiple misfire' ie P0300

It sounds like the code wasn't turned off properly.

YEP. You should never 'turn off' that code. Sometimes you have to tweak the misfire tables, to compensate for a real lumpy cam, but never turn the P0300 code completely. unless its a race car.
