Taken of my 2013 E71 X6 50i. Used for about 1,500 miles until I sold my baby for an F15 X5. This plug and play remap made my X6 really come alive. I wish I would've got it earlier!
This plug and play tuner attaches to sensors in the engine bay and works with your factory DME tuning to remap your boost, timing, and fueling for optimal performance and reduced turbo lag. It's designed specifically for the N63 and N63tu motors.
Stage1 gains on the N63 are up to 40whp range on pump gas and up to 60whp range with the N63tu motor. With exhaust modifications and/or on racing fuels even higher power levels are possible.
PM for questions or pictures- $350 Shipped.
