We are currently offering a courtesy tune upgrade from our Stage X calibration (any version) to our new Adapt-X calibration that uses factory octane learning to support 87-93 octane.
In addition to this, if you already had an E50 map, you'll be upgraded to our new E30 map with increased performance.
Please fill out the form ONLY if you had a Stage X calibration. Order email to confirm proof of purchase is required.
