F22 Tuning
BMW's 228i, 230i, 235i, M240i, 2014–2021. Powered by the N20/B48/N55/B58 engine family. Our calibration ceiling on this chassis: 395 HP · 415 LB-FT.
Stage pricing for the F22
Cooling, downpipe, fueling — the ceiling worth chasing on factory turbos.

Build this stage Stage 3 methodologyBefore the M2 existed, the F22 M235i was BMW's answer to "I want something small, rear-drive, and quick without paying M money" — and it's still one of the best value-per-smile coupes the brand has made.
The split mirrors the bigger cars. The 2014–2016 M235i runs the N55 single-turbo six (around 320 hp) — the same engine as the 335i, with the same deep, cheap aftermarket (its story's on the F30 page). The 2016+ M240i stepped up to the B58 (335 hp), the stronger, more headroom-rich six (see the G20 page). Both are genuinely quick — a tuned M240i runs with cars costing far more — and both came rear-drive, with a manual option for the people who want it.
The honest notes carry over from their engine families: the N55's electric water pump and oil-filter-housing items, the B58's housing gasket. Sorted on a used example, the F22 is a lot of rear-drive fun for the money.
So the F22 is the small, cheap, tunable coupe that walked so the M2 could run — and on the used market, still one of the smartest ways into a fast BMW.

Set the F22 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.
