2011–2013 E70 X5 50i - N63 Twin-Turbo MSD85 - Performance Tuning
BMW N63 with MSD85 Performance ECU tuning software.
Will work in the following BMW models:
- We do not offer tuning for emission delete, we do not disable catalytic converter or secondary air pump systems.

Stage 1: 79WHP 110WTQ - stock hardware
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.
