I have same issues, running Azenis on weaves.
However, Seeing that I am 5 mph off at 25 in a 25 radar screen zone doesnt help me much. I'm worried about how off my speedo is up aorund highway speeds.

Just gonna cruise next to a friend while on the cell phone...

Exactly my point, what it is off at 25 is not the same as 55.
Using a buddy may not help if theirs is off too.

That's because you guys need to speed through highway construction zones at 90mph +. :p

I did the buddy method alongside my friend's 2004 E46 with my Tii. That probably is the best and safest method, come to think of it.

All our speedos have a fixed 5mph error built in. Look at your speedometer when the car is standing still. The needle sits about 5mph below the 10mph mark. With 195/65R14 tires my GPS shows the speedometer to be 5mph too fast at all speeds. When I switch over to the 195/60R14 tires, I can add a 3% error the the fixed 5mph error. I've had 2 GPS devices in this car, they always show the same thing.

Cheers
