Based on what I've seen the AP reads fast. Remember that the factory speedometer is only accurate to within ~4% so the faster you go the more it will be off.

The thing to keep in mind is that the measurements it provides should be used to show deltas rather than absolute figures(just like a dyno.) So as long as it's just being used to compare different maps its fine.
