Default Recalibrate Speedometer

So fr those of you that are running larger then stock tires, what have you been doing to recalibrate your speedometer?

Im going from the stock 20" tires that measures some where around 32." to a 35 x 12.5 that actually measures at 34.6" .

I have called 2 different dealerships that both want $100 to do the recalibration and they have both told me that they can come close but don't think they can get right on a tire that large.

So my options seem to be take it to them for a $100 and hope they can get it right or buy a Superchip Tirepaq for $170 and risk more warranty voiding. http://www.autopartsdealer.com/super...ntent=APD74151

Do I have any other options? What has everyone else done?

Thanks.
