The Camry's odometer can be off too. Everything is fairly approximate. I personally like to use interstate mileage markers (the longer the run, the better) or a GPS. I have a Garmin hiking GPS that shows current speed as well as distance.

Your 2575 figure is correct, however, for a 0.1 mile error in 4.8 miles (About 2%). And, your initial figure of 2522 is what I would have started at too. Personally, I suspect it is VERY close to the right number, Camry or no Camry!

I was looking at the truck speed gauge not Gryphon, so maybe that's right. Why is there a discrepancy b/w the Gryphon and Truck speedometers? I thought the Gryphon was supposed to correct the truck gauge when TS is accounted for. But yes, I'm definitely off .1 mile w/in a very short distance, so I think I need to crank it up a bit. Thanks guys!!!!
