i thought stock limiter was 155? speedo will indicate higher but not actually going that fast. if truely seeing 170 plus and getting over 8600 its tuned or broken. if your on it the rpms will lag slightly so you are actually getting more than 8600 most likely. mine is tuned to 8600 but never seen it i usually shift arounnd 8000-8300 on the track.
