Yep.  Going from 3.9:1, for instance, to 3.54:1 will cause your speedo, 
odometer and trip meter to indicate about 11% low; e.g. if you're 
indicating 60MPH you'll be doing about 67.

You can:

1) get new gears for the odometer/trip meter and get the speedo calibrated,

2) get an inline ratio adapter,

3) get a GPS with real-time speed readout

4) get good at multiplying by 1.11 in your head
