Depends Vik... Usually, after, shall we say, a "encounter :lol: " at traffic lights, it will require a re-start, but sometimes, if im just giving it a bootfull (not floored), it will go onto 3 cyl's, then if I coast for a few hundred metres, it "may" right itself, its only done this twice though. But, generally, if you floor it, and stay on it for up to 5 secs, it will overboost, and will require a re-start.
