The Lethal Performance RTD4 Flash Device, or HP RTD4, does not inherently contain a tune file. Instead, this RTD4 device serves as the medium to transfer a custom tune onto your vehicle. Therefore, any adjustments, such as removing the top speed governor, depend on the specifics of the custom tune provided by whoever writes it. The Lethal Performance RTD ensures compatibility and ease of use in managing your vehicle's performance upgrades.
