*M-Boot: M-Boot was developed by Mission Performance as an additional solution for all of our returning customers that either want to upgrade performance stage or "temporary" go back to stock for a dealer visit. Since M-Boot is a custom written bootloader for the Fxx chassis, there is no additional chip/hardware needed to be added to the ECU. In addition of having the ability of reflashing the computer without sending it into our offices, M-Boot offers one very unique feature that no other company can offer at this point. After installation of M-Boot, your engine computer will never need to be updated at the dealer. That means that to the dealership, your engine computer will always show as up-to-date, factory original and in most cases, your tuned computer will not get reflashed to factory state.
