Heard some dude hit 160 mph in his stock RS Sunday morning. >
So what does it show when you're not moving? If there is speedo error, it's not the same percentage of error across the entire range. FYI, I have a Garmin GPS that confirms the speedo is money.Keep in mind that there's usually a bit of error built into the speedo. He may have read 160 and really been going 150. I'm pretty sure the speedo in my RS Q50 reads about 5% high.
