Raise or remove the electronic top-speed limiter.
Also known as: vmax · v-max · speed limiter delete · top speed limiter · derestrict · remove speed limit · governor delete · 162mph limiter
Speed-limiter removal (Vmax) raises or removes the electronic top-speed cap the ECU enforces — for example the common 250 km/h / 155 mph gentlemen's limit — for track and autobahn use. It changes only the limiter, not power. Tyres must be rated for the intended speed; it's a track/derestricted-road feature.
Softechpro Solutions applies emissions/diagnostic modules (DPF, EGR, AdBlue, DTC off, swirl flaps) automatically and supports Stage power and character features via credits, correcting the checksum across ~1,400 firmwares — on Windows & macOS.
