Unlock a sporty BMW factory exhaust burble with professional ECU coding by Modstock. We specialise in OEM-style burble activation on modern BMW B48 petrol models, including vehicles with a locked DME. No remap required, no engine warning lights – just refined, factory-correct sound.
Our burble coding activates BMW’s dormant exhaust sound logic, delivering enhanced overrun sound on lift-off and downshifts in Sport / Sport+ modes, just as found on select factory performance models.
