The F06 is the 6 Series Gran Coupe — the four-door version of the F13 coupe, BMW's elegant full-size GT with rear doors and a fastback roof. Same engines as the rest of the range: the 640i N55 six (320 hp), the 650i N63 V8 (450 hp), and the M6 Gran Coupe S63 V8 (560 hp) — the four-door M6 that rivaled the M5 of its day.

Each builds like its engine does across the lineup (see the F13 page). The Gran Coupe just adds usability to the grand tourer — and the M6 Gran Coupe in particular is a rare, elegant 560-hp four-door now attainable used.

So the F06 is the four-door GT: F13 grand-touring character, the practicality of doors, and an M6 that took on the M5.

ANSWERED

Before 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.
