The  best performance software available for your M54 being swapped into another chassis.

ECU can be shipped to us for programming or we can use the TRM Flashing Tool to flash your Car/ECU remotely if you have a KDCAN cable. A flashed ECU is also available if you select “buy an ecu”, though subject to availability. Email first if you would like an ECU provided to inquire about timeline for shipping.

For CAM tunes, or just to get the most out of your car, we recommend a custom tune.
