Stage pricing for the F20
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 F20 is the 1 Series hatchback — BMW's rear-drive hot hatch, sold across Europe but never offered in the US. The line tops out with the M135i and later M140i, running the N55 then the B58 six (around 320–340 hp) in a small, light, rear-drive body — effectively a 2-series coupe's running gear in a practical five-door.
They tune like every N55/B58 (stories on the F30 and G20 pages), which makes the M140i in particular a genuine pocket rocket. The base cars run smaller fours and threes. Forbidden fruit for US buyers, but a real, buildable rear-drive platform underneath.
So the F20 is the rear-drive hot hatch the US never got — small, light, six-cylinder, and as tunable as its bigger siblings.

Set the F20 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.
