Is there a gm cluster upgrade + mileage program shop in Chicago I should use instead?
Most local Chicago shops don’t offer gm cluster upgrade + mileage program as a bench service — they’d send the part to someone like us anyway. Going direct saves the markup and shortens the timeline. Total round-trip from Chicago: typically 5-7 days.
Can you upgrade a base Silverado cluster to an LTZ digital one?
Yes. We program the upgraded cluster to your VIN, sync mileage, and clear anti-theft. The instrument options light up as the upgraded trim.
Will the truck start after install?
Yes. We clear the Passlock / theft-deterrent counter so your existing keys work on the programmed cluster. No dealer trip required.
Do you do mileage rollback?
No. We only sync to the actual recorded mileage of your truck (from ECM, BCM, or your original cluster). Rollbacks are illegal under federal law.
