Any GM techs out there? Or anyone with some experience trying to reprogram a new LLY Duramax for a tire swap from 245's to Revo 265's?
Working with my saleman, and after two tries the speedo and odometer are still off by 3.9%, exactly the difference in tire height between the stock tires and my new ones. I would like to get this right, but I guess if it can't be done then it can't be done. The thing that gets me is that having an inaccurate speedometer & odometer is illegal and I don't understand how GM can prevent this change from being made to the vehicle?
We went to the flats too. I dipped a tire on the rental car onto it just to say I’ve been there,but it was still pretty soft from winter melt. After seeing some moron in a BMW suv get dragged out of the muck I had no intention of repeating his stupidity.
