Yeah not all vehicle have chip. Old vehicle dont have chip. Some car go maximum speed because the engine injector doesnt get enough air in the cylinder. The smaller engine the lower maximum it can go. The engine doesnt have enough air to make fire with gas. That is why all special kind of racer car that go at least 300 MPH have special kind of engine. Like they have turbo on top above the front hood. That is for air vacuum to get extra air into the engine during they go very high speed. My car engine is kind of small and it couldnt go over 105 MPH few years ago but now it is much older and couldnt go over 95 MPH. It didnt stall or shake when I go that 105 MPH. It just got stuck to that 105 MPH forever, unless I go downhill, until I pull off the gas pedal. So not all vehicle have chip. Only the newer vehicle has it.
