2010–2013 E70 X5M - S63 Twin-Turbo MSD85 - Performance Tuning

• We do not offer tuning for emission delete, we do not disable catalytic converter or secondary air pump systems. 
• We do not offer tuning services to the state of California.

BMW S63 with MSD85 Performance ECU tuning software.

Will work in the following BMW models:

Gains: 62WHP/75WTQ at the wheels on our Mainline ProHub 5000 dynamometer. 

We only offer one flashing type for this car (Bench Flash).

BENCH FLASH: Remove the ECU/DME and mail it in. We will create a full backup image of your ECU/DME without opening the lid or any physical damage to it. We then upload the tune. This is the safest way, as we can have a full backup of the entire ECU/DME content.

If you're a local in the Seattle area in Washington, you're welcome to stop by and we can do this in person without having to remove the DME from the vehicle.

Performance tuning modifies torque limiter maps, boost levels, fuel maps, ignition timing advance maps and more. All to help safely increase HP/TQ, while keeping good drive-ability and factory fail-safes/limp protection in place.
