I've got a friend who's pretty good a doing custom programming on diesels, cars, etc... So here's my question, could the 6th gear limit be programmed out of the factory settings or is it just one of those things that you can't get around witout using the TRE? With the right connections would it even be possible to even read the programming or would that require specialized software? This may sound stupid, but I thought this would be the best place to ask.
