i own a 4th Gen 4 Runner and was wondering if the Dealer could "reflash" the computer to accurize the odometer and fuel calculations as I intend to move up to 275 70 R17's??????????

I owned a 2001 Dodge Ram TD and the dealer could/would "reflash" the computer if you asked, when you changed tire size!

 

normally that isnt something a dealer would touch... but there are units out there like the superlift truspeed that can do stuffl ike that.... also several companies make power programmers, im just not sure what the exact applications are in relation to the toyta market
