*M-Boot:  M-Boot was developed by Mission Performance as an additional solution for all of our 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, 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 great features as Flash-Counter freezing and Calibration ID spoofing.
