I have a HyperTech speedometer calibrator to compensate for my lift and larger tires. Since that all it does is adjust for the correct speed and odometer I have not imposed on my factory warranty. It was dealer installed conversion.

only option is the hypertech one just mentioned, otherwise you will have to go custom programming route either via Blackbear tuning or by using laptop tuning software like EFIlive or HP Tuners. Chris White might be able to do it as well, but you would need to message him and find out.

 

Dealers do not have a way to do this anymore.
