The ‘Popcorn’ (Hard Cut) Limiter tells your vehicle’s ECU to cut fuelling to the engine at a set RPM (normally 4300rpm), causing it to bounce off the limiter, making a diesel sound more like a petrol engine.This is primarily for cars produced by the Volkswagen Group, but we will consider applying it to other vehicles after analysing the relevant diagnostic data. This will not change engine performance, only how it sounds.
NOT RECOMMENDED! Due to long term engine damage!
