Custom Chevy 5.3L tune file

This allows you the consumer to request a custom tune file from a 5.3L LS engine. The file is based off a 2006 Chevy Silverado 5.3L OEM file that will be adjusted to where you need it for your application. This may include: code changes, power enrichment EQ changes, Transmission Timing based on MPH, Vats removal, Flex fuel deactivation where applicable, AFM/DOD deactivation, and other things required. This DOES NOT include: ETC adjustments, Fuel capacity adjustments, Spark timing (at this moment), and other things that require a vehicle present to ensure proper operation. Once purchased files will have your requested changes and will be able to have small things adjusted once more at no cost.
