BMW's X6 xDrive35i, X6 xDrive50i, 2015–2019. Powered by the N55/N63 engine family.
Stage pricing for the F16
Cooling, downpipe, fueling — the ceiling worth chasing on factory turbos.
Build this stage Stage 2 methodologyBigger fueling, often a hybrid or Phantom turbo. Per-car.
Build this stage Stage 3 methodologyThe F16 is the previous X6 — the F15 X5 with the coupe-SUV roofline (2014–2019). Same engines: the xDrive35i N55 six (around 300 hp), the xDrive50i N63 V8 (around 445 hp), both tuning as they do in the X5 (see the F15 page). The X6 just trades cargo for the fastback look.
On the used market it's the style-conscious version of the F15 value play — the same buildable N55/N63 platforms, more aggressive shape. The honest notes are the same: buy on condition, especially the V8.
So the F16 is the used coupe-SUV: the F15's tuning, the sleeker body.

Set the F16 as your garage vehicle and the rest of the store filters to what fits it.
Set vehicleBefore you tune.
Will my dealer flag the tune at service?
The bootmod3 flash is non-destructive and reversible. Revert to stock before a dealer appointment and the ECU is back to factory in a few minutes; re-flash after service. We document the revert step in writing so the next person opening your file knows what's there.
Is it safe for the engine?
Every tune we ship has been datalogged on the car it was written for. We look at knock counts, fuel trims, boost behavior, and intake temps before we sign off. If the numbers don't sit right, we revise. That review and the revision policy are built into what the tune costs.
How long until I have a working tune?
Most calibrations turn around in a few days. We log, review, and revise before anything ships — we would rather get it right than get it out fast.
Can I go back to stock?
Yes. bootmod3 supports a stock revert that returns the ECU to factory calibration in under five minutes. The flash is non-destructive — nothing in the BMW DME is permanently modified. Most owners revert before trade-in.
