Stage pricing for the F93
Cooling, downpipe, fueling — the ceiling worth chasing on factory turbos.
Build this stage Stage 2 methodologyThe F93 is the M8 Gran Coupe — the M flagship with four doors and a longer roofline, the most practical way into M8 ownership. Same S63 V8 (617 hp Competition), same hardware as the F92 coupe (full story there); the gran coupe just makes it usable for four.
It sits in interesting territory: nearly an M5's practicality with the M8's badge and price, so choosing between them is more about positioning than capability. Either way it builds like every S63 — deep headroom, a maintenance-aware V8, bought on history and tuned with proper supporting parts.
So the F93 is the four-door M flagship: M8 power and presence, in the body that seats the family.

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.
