Speedo way out.....

[Storm]

I put my GPS Snooper in the Supra last weekend and it highlighted how far out my clock is on the car.
I still have the original KM clock with a sticker over the K. I have the speedo convertor fitted so it now reads in MPH.
However, the clock is out by 7mph & even at 30mph on the GPS I am barely doing 25mph on the Speedo.
Should the convertor be this far out as I am thinking of changing it for a better more accurate one.
Anyone elses speedo out this far.

IIRC most speedo's are out around 10%.

i think 160 on a Supe clock is around 148 mph on a GPS.

If you have a Thor speedo converter these are apparently adjustable to compensate for any inaccuracies.
