A modified HP Tuners L5P E41 ECM is required to allow flashing. Select an option to purchase or if you already have a modified ECM. Purchasing an ECM will require a Core Charge.
A core charge is collected to insure our ECM exchange. We will provide you with a modified ECM upon purchase. Your core charge is immediately refunded when your factory ECM has been received by us. This exchange leaves your vehicle with little to zero down time.
The MPVI2 is required to flash your modified L5P ECM. Select an option to purchase or if the unit is already owned.
