I'm running 35" Nitto Trail grapplers and my flashpaq is set at 33" and the speedo is dead on per my GPS. The flashpaq has the stock wheels and tires set at 30.75 for my 17" rims and 255-75-17's.

What he said. Start with the actual measurement, not mfg's listed height, and then decrease tire height until you get it right on with the gps.
I have 315/75/16's. Mfg says 34.8. Actual mounted height, 33.5. Set the Flashpaq to 33.00 to get the speedo somewhat close to GPS. (Spent an hour re-setting and checking and re-setting and checking, and never got it to match)
My old ProCal seemed much better at setting the variables to get the speedo correct...
