Just got a GPS unit last night so ofcourse I had to go for a bit of fun on my lunch break today. Held speed at 130 mph for about 5 sec. and then came back down to semi-legal speeds. Once I got back to work I checked the high speed log and it said only 111 mph.
I know that all speedo's are off from the factory, question is does this difference seem a bit much or is it about right? I know the GPS is good ( I work on it in military ) so I'm not questioning that, just the differential amount.
