Default why is my speedo of by 15mph?

When I go racing my speedo says I'm going through the traps @115 mph when its really 100mph. I know the tire size hasa something to do with it but damn 15mph?

does anyone else have this problem? could it be the H22 trans sending the wrong current to the speedo? also I guess my 120 speed goenor is kicking in @105 WTF?

The mph on your timeslip is an average of your mph while going thru the traps... its not the speed you were going at the end.

how is that possible because you are accelerating down the entire track?

if it took the average it would be in the 50mph range

Trap speed is an average between the last 66 feet and the finish line..

Has your cluster ever been taken apart for anything? I had a friend that put on indiglo gauges like about 4 years ago and he kept moving his needles and damaged it. I'm not sure if your problem is that simple, but it's just something that would be obvious in case you ever did anything.
