just started doing it 3 days ago. seems to do it at just about any RPM, although each time it was while accelerating. the first morning it did it a couple times in succession and then cleared up, didn't happen again. last night it did it just once under light acceleration, i probably wasn't even seeing any boost. just fell flat on it's face and then picked back up again. wtf?! could my MAF be getting wet? :shrug:
