I took a hit in indicated MPG when I used my gps to calibrate my MPGuino.

differences in speed is hard to get nailed down as it is hard to look in two places at once but distances are easier. when using a GPS make sure you have a good signal, and start moving as quick as you can on a highway trip as even when stopped the couple feet difference that the GPS calculates every second add as distance traveled up while stopped, but for the most part average out while moving. Go at least 10 miles and compare the GPS trip-o-meter to your car's (or guino's) trip reading.
