I'm confused by this statement....seems to me if you put taller tires on a vehicle, the above numbers should be reversed. GPS (actual) speed 44 mph and indicated speed 40 mph.

At least, that's what's happening with my Wrangler with the tall tires. When the speedometer indicates I'm driving 45 mph, I'm actually traveling about 50 mph and have to keep an eye out for the law!

Good catch !
The taller tire has less revolutions per mile

My truck has slightly larger tires
When my truck says 55 ...
My GPS says 56.4

Thanks for this, I bought one. I could never get Forscan to connect so this seems like the next best option.

I’d find it much less painful to pull a dash apart, than use than use bloated Windows to run “ForeSkin”.

So 140 for the device , records a flash which the dealer can use as leverage or try to at least if something happens . Maybe won't come of anything other than a headache but still . My dealer said they can recalibrate for 70. They wanna pick at the brain is rather them do it , leave a trail that leads back to them for lower price..... Just my opinion probably not worth much.
