Speedhut Gauges

Just something I wanted to add here. If your car accelerates very fast, the GPS speedo won't keep up and will not give you the actual speed you're going. I am noticing this problem with mine. I let off the throttle after a hard run and the needle is still going up for another second or so before it starts dropping back down. I've brought up this issue to Speedhut and sent them a video. They said the speedo is functioning as it should but the car is too fast to keep up (I know what a horrible problem right?). They offered to have me send it in at no cost (except shipping) to speed up the needle, but it may result in a jumpy digital looking needle they said. They're supposed to send me a video of what it would look like sped up so we'll see. I may just leave it. I'm not paying attention to the speedo very much anyway when I'm in it hard. Mostly the road and rpm's.
