Stage pricing for the F12
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 F12 is the 6 Series Convertible — the open-top version of the F13 coupe, BMW's grand tourer with the roof down. Same engines: 640i N55 (320 hp), 650i N63 V8 (450 hp), and the M6 Convertible S63 V8 (560 hp). It's the most relaxed way to own a 6 — built for boulevards and coastlines more than apexes, the soft-top adding weight and trading a little rigidity.
Each builds like the F13 (see that page); the convertible just leans further toward cruising. The honest notes are the V8s' upkeep and a used drop-top's need for a careful inspection.
So the F12 is the open-top grand tourer: the F13's range, the roof down, the GT experience before the 8 Series took over.

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.
