To clarify, GDE advised I should uninstall the GDE tune and reinstall the original factory ECU data before taking the sprinter to the dealer for the update. i am reluctant to do this, and still unclear on the need/benefits for a California vehicle since the recall prevents the GDE tune from being reinstalled to my knowledge.Since when does GDE offer a tune for California vehicles?
If you can back that up, a lot of other people would be interested in the file :p
Will the dealer detect the GDE tune during the recall work and somehow void any warranty work? .. Will the recall tune not work right with the GDE data installed? .. or was this just GDE's standard line that doesn't apply to California ... I still don't know.
