I doubt a dealer would do it, even if they could (though maybe the
PIWIS has the capability?).
When Scott (
Softronic) first came out with the Snap-Flash, which can raise the rev limits on MT cars, he told me that because of the separate Tiptronic controller it wasn't possible to change Tip rev limits with his software (except maybe for 5th gear IIRC). I've never seen any mention of anyone reprogramming the Tip controller.
